Design system reference

The single visual surface for design-system review. Colors, type, and components live here. Every shared component in @viatrm/ui lands with a section below in the same PR.

Token values shown are placeholders pending UI/UX confirmation. See packages/ui/src/styles/tokens.css and CLAUDE.md §8.3.

Colors

Four-layer cascade per CLAUDE.md §8.3: --via-* (brand, locked) → --client-* (per-Client overrides, defaults to Via) → --product-* (brand-locked product accents) → --color-* (resolved tokens components reference).

Via brand (locked)

Layout primitives

Low-API building blocks. Pages compose them rather than asking each for variants. Every primitive is mobile-first, tokens-only (no ad-hoc spacing or color), works at 320px, and meets WCAG 2.2 AA. Density is tighter than typical SaaS marketing UI to suit data-and-workflow screens.

Page

Outermost wrapper for every route. Renders as <main> so each page has exactly one main landmark. Four widths gate the readable-line-length problem on wide screens while still letting dense surfaces own the viewport.

Widths

narrow (max-w-3xl) for forms · default (max-w-7xl) for most ops UI · wide (max-w-screen-2xl) for dense tables · full for app-shell pages that own the viewport.

Responsive padding

px-4 py-6 on mobile · sm:px-6 sm:py-8 · lg:px-8 lg:py-10. Resize the viewport to see the step-up at 640px and 1024px.

Page padding scales with viewport.
Accessibility & responsive notes
  • Renders <main> by default — one per route.
  • Override with as only when a route legitimately has no main (rare).
  • Mobile-first padding never drops below 16px so touch interaction stays comfortable.

PageHeader

The top of an index/list page. Always carries the page's single h1. The actions cluster reflows below the title on narrow viewports — the title is never truncated to make room for buttons.

Default — Experiences index

Eyebrow + title + description + primary action. Realistic admin landing for the Experiences module.

Experiences

Reusable definitions of structured engagements your participants join.

With breadcrumb meta and tabs slot

Meta renders above the title (breadcrumbs, back-nav). Children render below the header — typically tabs or filter bars.

Sessions

Instances of an Experience with dates, capacity, and deadlines.

Accessibility & responsive notes
  • One h1 per page — pair with at most one PageHeader or DetailHeader.
  • Actions wrap to their own row at <640px so the title gets the full line.
  • Eyebrow is short, uppercase, neutral — use it for category, not status.

Section

Labelled region inside a Page. Always renders <section aria-labelledby>; the heading level is configurable so nested sections build a meaningful h1 → h2 → h3 outline.

Default (h2) with description and actions

The everyday section header. Title left, actions right; both wrap on narrow viewports.

Active experiences

Published and accepting applications.

12 experiences across 4 product lines.

Nested (h3)

Use headingLevel=3 inside an existing Section. Don't skip levels — h2 → h4 confuses screen-reader outlines.

Accessibility & responsive notes
  • Outer section adds aria-labelledby automatically — no extra wiring at the call site.
  • headingLevel must respect outline order: h1 (PageHeader) → h2 (Section) → h3 (nested).
  • Actions row uses the same wrap discipline as PageHeader.

Stack

Vertical flex with a discrete spacing scale. Use Stack instead of ad-hoc space-y-* — the scale is the rhythm of the product.

Six steps. md is the default; xs/sm for dense rows, xl/2xl for separating major regions.

  • Use Stack for vertical rhythm; Inline for horizontal.
  • align controls cross-axis (items-start/center/end/stretch).

Inline

Horizontal flex with the same spacing scale as Stack. Wraps by default so dense rows of chips, metadata, and actions reflow gracefully at 320px.

Filter row

Status chips + sort selector. Wraps onto multiple rows at narrow viewports rather than overflowing horizontally.

justify=between for header bars

A common pattern: a label on the left, actions on the right, wrapping cleanly when there's no room.

Showing24 of 184participants

wrap=false for fixed-width toolbars

Set wrap=false only when overflow is impossible by construction (icon-only toolbars in a known-width container).

Accessibility & responsive notes
  • Wraps by default; never produce horizontal scroll on a known viewport.
  • Default gap="sm" (8px) — tighter than Stack's default since horizontal rows read denser.
  • justify="between" is the workhorse for header bars.

Container

A bordered surface for grouping operational content. Deliberately not called "Card" — operational UI uses surfaces for structure, not for marketing-style content cards.

Variants

default for the everyday surface · subtle for nested/secondary blocks · flush for tables and lists that own their own internal padding.

Accessibility & responsive notes
  • Default padding is md; flush variants auto-drop to none.
  • Shadow is intentionally minimal — borders carry most of the visual hierarchy in dense layouts.
  • Pass as="article" for content that semantically stands alone (e.g., one item in a list of records).

EmptyState

What fills a list, table, or section when there is no data yet. Operational empty states describe the gap and offer the next step — they are not marketing slots.

Default (md) — whole-section emptiness

For an empty Experiences list, an empty Requirements panel, etc.

No experiences yet

Create your first Experience to start defining structured engagements for participants.

Small (sm) — inline empty

For empty inline lists inside a larger Section (e.g., a Session with no Requirements yet).

Requirements

No requirements configured

Add a requirement to define what participants need to complete.

Accessibility & responsive notes
  • No role="status" — empty state is static content, not a live region. Adding aria-live would cause unwanted announcements.
  • Title should be the noun, description should explain the gap, action should be the next step.
  • Icon is decorative and aria-hidden — never the sole signal.

SplitLayout

Main working surface + secondary <aside> for status, metadata, owners. Stacks below the main column on viewports under lg (1024px). DOM order is always main → aside, so the working content reads first.

Experience detail layout

Main column owns the description and sessions table; aside owns status, ownership, and key dates.

asidePosition=left

Visual order swaps on lg+; DOM order stays main-first so screen readers and reading order are unaffected.

Main content

DOM order is still main → aside; only the visual position is swapped on lg+.

Accessibility & responsive notes
  • Aside is a real <aside> landmark — name it via its content (no ARIA needed).
  • DOM order is always main → aside. asidePosition only affects visual order at lg+.
  • asideWidth is sm (16rem) / md (20rem) / lg (24rem).

SidebarLayout

App-shell layout with a persistent left navigation. Desktop (lg+) shows the sidebar inline; mobile collapses it behind a toggle that opens an overlay drawer scoped to the layout's bounds.

Admin shell

Realistic admin nav with the page header and a small data surface inside. Resize the viewport below 1024px to see the mobile drawer behavior.

Accessibility & responsive notes
  • <nav aria-label> — required so it's distinguishable from page-internal nav (tabs, breadcrumbs).
  • Toggle reports aria-expanded / aria-controls; Esc closes the drawer; click on the overlay closes.
  • Drawer transitions are CSS-only and honor prefers-reduced-motion.
  • Hard focus trap is deferred to a future Dialog primitive; for now, navigate the drawer links with Tab and close with Esc.
  • Nav links should set aria-current="page" on the active route (this primitive doesn't own routing).

DetailHeader

Top of an entity detail page (one Experience, one Session, one Participant). Sibling to PageHeader; a page uses exactly one of the two.

Requirements

No requirements configured

Add a requirement to define what participants need to complete.

Components

Each component PR adds an entry here showing variants, sizes, states (default, hover, focus, disabled, loading), and any accessibility-sensitive patterns (focus rings, ARIA, keyboard).

Button

Primary action element. Real <button>; never <div onClick>. Defaults to type="button" so it doesn't accidentally submit a form.

Variants

Six variants. Filled (primary / secondary / tertiary / destructive) use the resolved color tokens — they re-skin per Client and per product context automatically.

Sizes

Three sizes. All sizes meet the 44×44px minimum touch target on mobile per CLAUDE.md §8.1 — sm is visually compact but still tappable.

States

Default · disabled · loading. Hover and active states have subtle visual feedback (brightness shift on filled, neutral background on outline/ghost). Focus-visible ring is keyboard-only.

With icons

Leading and trailing icon slots. Icons are aria-hidden — the button's accessible name comes from its text children.

Full width

For modal footers, mobile CTAs, narrow form columns.

Accessibility notes
  • Real <button>; keyboard activation via Enter and Space comes free.
  • focus-visible outline (2px, 2px offset, neutral-900) — appears on keyboard focus, not mouse click.
  • loading=true sets aria-busy="true", swaps the leading icon for a spinner that honors prefers-reduced-motion, and disables interaction.
  • disabled drops opacity and disables interaction; the label remains in the accessibility tree.
  • Touch target ≥ 44×44px via min-h-11 min-w-11 on every size.
  • Icon-only buttons must wrap the icon's label in <span className="sr-only">.
  • Outline variant border uses border-neutral-400 (≈ 2.45:1) — the same documented WCAG 1.4.11 deviation noted on FormField. Revisit when the design system review picks up.

Badge

Inline label for status, category, or count. One subtle pill style — color is always a redundant signal alongside the label, so the badge stays usable for color-blind readers and in forced-colors mode. Use a leading dot for at-a-glance scanning in lists.

Tones (with dot)

Status pills. Tone communicates lifecycle/state; the text label always carries meaning.

DraftUnder reviewPublishedAction requiredRejected

Tones (no dot)

For category tags and counts where lifecycle isn't the meaning. Keep the surface calm — operational lists fill with these.

Study abroadFaculty-ledTrainingEvent12 pending

Inline with row content

Composes inside DetailHeader status slot, table cells, list items. Padding stays tight so dense rows don't expand.

Rome Study AbroadPublished
Accessibility notes
  • Color is always a redundant signal — the text label carries the meaning. Forced-colors mode keeps the pill legible because the surface and label switch with the system theme.
  • The leading dot is aria-hidden — screen readers announce the label only, with no duplication.
  • Renders as an inline <span> — drop it inside paragraphs, table cells, or the DetailHeader status slot without breaking layout.

ProgressBar

A status output (role="progressbar"), never a control. Determinate reports known progress (0–100, clamped) and exposes aria-valuenow. Indeterminate reports work of unknown duration and omits aria-valuenow — no fabricated percentage. First consumer: the ImageField upload lifecycle.

Determinate

Known progress. The fill width animates (and snaps under reduced motion). The required label is the accessible name; any visible caption is optional supporting text.

Indeterminate

Unknown duration (e.g. server-side processing). A segment travels the track; under prefers-reduced-motion it becomes a static striped fill that still reads as in progress.

Sizes

sm (6px) for compact/inline contexts, md (10px) default.

Tones

Brand default plus semantic success / danger — always paired with caption text, never color alone. Danger is a general capability; ImageField failures transition into an actionable error state rather than lingering as a red bar.

Uploading…
Saved
Stalled

With caption — the honest upload lifecycle

Uploading (determinate) → Processing (indeterminate) → Saved (success). The bar only turns green after the backend confirms persistence, never merely because byte transfer hit 100%.

Saving…62%
Processing…
Saved
Accessibility notes
  • role="progressbar" with a required accessible name via the label prop.
  • Determinate exposes aria-valuenow / aria-valuemin=0 / aria-valuemax=100; indeterminate omits aria-valuenow so assistive tech announces busy, not a false number.
  • Motion respects prefers-reduced-motion — determinate width transitions are disabled; the indeterminate segment becomes a static striped fill.
  • Meaning is never color-only: the optional caption carries state as text.
  • No keyboard interaction — it is a status output, not a control.

ImageDropzone

A domain-blind image acquisition surface. One real <button> — click, Enter/Space, drag & drop, or paste (while focused) — that emits a candidate File and typed validation outcomes (unsupported-type, file-too-large, multiple-files, empty-file). It owns no preview, upload, or persistence — those belong to ImageField later. Supported formats and the size cap come from the shared ingest policy (PNG, JPEG, or WebP · up to 10 MB) and are shown in the surface. Try the live examples below; nothing uploads.

Default

Full-width acquisition surface. The whole box is the button (no nested link); 'browse' is emphasis only. Click / Enter / Space open the file picker; drag a file onto it; focus it and paste.

Waiting for an image…

Compact variant

Layout density only — identical behavior, validation, and events. For tighter contexts.

Waiting for an image…

Invalid (with FieldError)

Inherits FormField context like TextInput: danger border + aria-invalid, with the consumer-rendered FieldError below. The primitive emits typed reasons; the consumer owns the copy.

That image is too large — max is 10 MB.

Disabled

Disabled on both the button and the underlying file input; no hover or drag emphasis.

Replacement seam (children)

Non-interactive children fill the surface (the PR4 replace target). A drag-active overlay reads 'Drop image to replace' and dims the preview. Explicit Replace/Remove controls live adjacent in ImageField later — never nested inside this button.

Waiting for an image…

Accessibility notes
  • The surface is a real <button> — native keyboard (Enter/Space) and focus, no custom role. No nested interactive element, so there is no button-in-button.
  • Accessible name comes from the visible instructions (default) or aria-label (replacement seam). Instructions are text, never icon-only.
  • Drag & paste are supplementary; browse is the guaranteed keyboard path. Paste is scoped to the focused surface — no global listener, so it never interferes with other inputs.
  • Errors associate via FormField context (aria-invalid + aria-describedby). Client validation is UX only — the server ingest re-validates every byte.
  • Full-width, ≥44px target, wraps cleanly at 320px. Only subtle color transitions, disabled under prefers-reduced-motion.

ImageEditor

A domain-blind crop / zoom / rotate / reframe editor wrapping react-easy-crop (6.x, MIT) behind the Phoenix API. Desktop in a Dialog, mobile in a full-height Drawer (fixed header, scrollable body, sticky footer); presentation="auto" picks by viewport. It returns edit instructions on Apply — no canvas runs during interaction; the consumer prepares the Blob later via prepareEditedImage.

Editor — multiple aspect presets, zoom, rotate, reset, destination preview

Consumer-provided aspect presets (numeric + original); native-range zoom; explicit Rotate 90° and Reset; an optional live destination preview (nav chip). Apply returns pre-rotation source-space crop pixels + rotation/aspect/zoom.

Opens a Dialog (desktop) or full-height Drawer (mobile). Applying returns edit instructions; nothing is uploaded or persisted.

Constrained — single aspect, rotate unavailable

allowRotate=false removes the rotate control; a single preset locks the aspect. Zoom and reset remain. Density-only configuration — behavior is unchanged.

Source decode failure

When the source can't be decoded, the editor shows an actionable message and disables Apply. Recovery is Cancel — the editor never takes on acquisition responsibilities.

Accessibility notes
  • Honest limitation: fine crop repositioning is pointer/touch only (true of every canvas cropper). Task completion never depends on it — aspect presets (a radio group), the zoom range, Rotate, Reset, Apply, and Cancel are all keyboard operable, and the crop auto-centres, so a keyboard/screen-reader user reaches a valid result without dragging.
  • Desktop Dialog / mobile Drawer are native <dialog>: browser focus trap, Esc, and focus restoration. Esc / backdrop / Cancel discard — closing never silently applies edits.
  • The crop surface is a labelled group with an accessible description; the help text uses neutral guidance that never makes pointer interaction seem mandatory.
  • Targets ≥44px, 320px-safe, browser zoom enabled; motion is delegated to the overlay + cropper and respects reduced motion.

ImagePreserveEditor

The "preserve" sibling to ImageEditor above: where ImageEditor frames an image (crop/zoom/aspect to a target shape), this surface preserves it — the whole asset stays at its natural geometry, and the job is confidence, not composition. Preview the original on a transparency checkerboard (so alpha is visible), rotate if it isn't upright, and commit. There's deliberately no crop, no zoom, and no aspect selector. It is domain-blind and returns the same ImageEdit contract ImageEditor does. In the real product it never mounts standalone — ImageField mounts it internally for a preserve-intent ImagePurpose (see the "Preserve surface" example under ImageField below, which exercises the full upload path). The demos here open the editor directly against a fixed demo asset instead, so the surface is reviewable without an upload step.

Default — rotate, reset, destination preview

A wide, transparent-background demo mark, so the checkerboard is showing something real. Explicit Rotate 90° and Reset; an optional live destination preview. Apply returns a whole-image crop (source rect, pre-rotation) plus the chosen rotation.

Opens a Dialog (desktop) or full-height Drawer (mobile) — no crop, no zoom, no aspect selector. Applying returns edit instructions; nothing is uploaded or persisted.

Rotate unavailable

allowRotate=false removes the Rotate/Reset controls entirely — the surface becomes pure confirmation, nothing to adjust.

Source decode failure

When the source can't be decoded, the editor shows an actionable message and Apply is disabled. Recovery is Cancel — same posture as ImageEditor.

Accessibility notes
  • No pointer-only task: with rotate enabled, Rotate 90°, Reset, Apply, and Cancel are all keyboard-operable buttons — there is no drag/reposition affordance to route around (unlike ImageEditor's crop, this surface never repositions anything).
  • Desktop Dialog / mobile Drawer are the same native <dialog>-backed primitives as ImageEditor: browser focus trap, Esc, and focus restoration. Esc / backdrop / Cancel discard — closing never silently applies a rotation.
  • The checkerboard preview is presentational (transparency is visible to sighted users checking the mark); the help text under it states in words that the whole image is kept and nothing is cropped, so the same fact doesn't depend on seeing the pattern.
  • Targets ≥44px, 320px-safe, browser zoom enabled; rotation respects reduced motion.

ImagePreview

A domain-blind, non-interactive image preview — managed, external, or blob: URLs — that preserves aspect ratio and degrades gracefully when an image is broken. A pure renderer: it owns no object URLs (ImageField does) and knows nothing about storage.

Image

Renders any URL with its alt text.

Brand image

Aspect-ratio frame

Constrain the frame to a consumer-defined ratio; the image fits inside.

Brand image

Broken-image fallback

On load failure it shows a placeholder and keeps the accessible name — never a broken-image glyph.

Brand image

Empty

A null src shows a calm placeholder.

ImageField — the One Media Experience

The domain-blind composition of the image primitives — the full lifecycle: acquire → edit → prepare → upload → process → commit → change → remove → undo. Optimistic presentation, conservative persistence: the edited image appears immediately marked “Saving…”, and is only “Saved” once the backend confirms. Normal product code passes an ImagePurpose (Avatar / Preserve below) so the consumer declares an image’s role and ImageField resolves the editing surface, geometry, output, and destination preview — it does not hand-wire aspect ratios. The raw primitives example is retained only for platform work. The transports below are fakes — nothing is persisted.

The demos below cover the complete workflow end to end: one Add entry + source chooser, Image URL staged review (nothing commits until “Use image”), a committed managed image that is itself the Edit affordance (Edit primary · Change · quiet destructive Remove — never three equal peers), a committed external image that explains why Edit is unavailable, loading / pending and error → retry states, deliberate Remove (confirmation, never a one-click delete), and Frame / Preserve purposes. On narrow screens the secondary Change + Remove fold into a “More actions” menu while Edit stays visible — resize this page below 768px to see it. Verbs are consistent throughout: Add image · Edit image · Change image · Remove · Use image.

Media source chooser (One Media Experience — one way in)

The single Add-image entry. One chooser lists only the sources a field supports today (no 'coming soon' placeholders); it's a compact anchored popover on desktop and a bottom sheet on mobile. Keyboard: arrows/Home/End move, Enter selects, Esc closes; outside-click dismisses. New providers appear by being present in the options.

No source selected yet.

Image URL review (editing happens before commit)

An external link is entered, previewed, and only 'Use image' commits it — entering or submitting the field never changes the active image. Editing an externally-hosted image is a whole-image review (no crop/zoom/rotate/straighten); a copy line explains the image stays hosted at its original location. A failed preview blocks Use image.

Add image

Enter a link to an image online.

No image confirmed yet.

Avatar purpose (frame · circular · 1:1 · straighten)

`frame` intent with a circular crop mask, 1:1 square output, zoom + rotate + Straighten, and NO aspect selector — the admin frames a face and can nudge a crooked photo level, presented as a circular avatar. Source MIME preserved (no forced PNG); the saved raster stays a plain square.

Profile photo
Choose a photo; we’ll frame it.

Remove profile photo?

This removes the current image. You can add another image at any time.

Straighten (frame · original ratio)

`frame` locked to the source's natural ratio with Straighten enabled — an orientation correction for a slightly crooked image. The Straighten slider (−15°..+15°) tilts the preview live; the minimum zoom rises just enough to keep the crop frame covered (no empty corners), and Reset returns it to 0°. Straighten is deliberately quieter than crop/zoom/rotate — a fix, not a design tool.

Scan or document
Straighten a slightly crooked image.

Remove scan or document?

This removes the current image. You can add another image at any time.

Preserve surface (confirm, don't crop)

`preserve` intent keeps the whole mark at its natural geometry — confidence, not composition: preview the original on a transparency checkerboard, rotate if needed, Apply. No crop, zoom, or aspect selector. (Client Logo is now a `frame` purpose locked to the source's natural ratio — this generic preserve purpose keeps the surface demonstrated.)

Brand mark (preserve)
Kept whole — confirm and rotate, never cropped.

Remove brand mark (preserve)?

This removes the current image. You can add another image at any time.

Low-level primitives (platform only) — Upload + Image URL, raw aspects

The escape hatch: raw `aspectRatios` + two sources, for platform development and regression. Product code should use a purpose above instead. Upload → editor → optimistic → committed; Image URL → debounced preview → Save; Replace / Remove (with Undo).

Failure → Retry

A failing upload restores the previous value and offers Retry (reuses the prepared image, no re-crop) or Choose another image.

Brand image

Deliberate removal — confirmation

Remove never happens from one click: it opens a confirmation (Cancel returns the current image unchanged; the destructive action runs the existing remove transport, shows a pending state, and clears the image only on success). Undo appears afterwards when the consumer supplies restore.

Brand image
Remove asks for confirmation first.

Removal failure → retry (external image)

On an externally hosted image (same confirmation as a managed one): the first confirmation fails, keeping the image visible with an actionable error; retry succeeds. No Undo — the confirmation is the protection.

Accessibility notes
  • One coherent field label + description; the sub-controls (source selector, dropzone, editor, URL input, Retry, Replace, Remove, Undo) are all keyboard-accessible.
  • The source selector is a labelled toggle-button group (role="group" + aria-pressed); switching source is non-persistent and the committed image stays authoritative until a save succeeds. The URL input pairs its validation error via aria-describedby; a failed external preview is a text warning (not color alone) and never blocks Save.
  • Status changes announce through a polite live region; progress announcements are throttled to deciles (not every event).
  • The optimistic state is marked “Saving…” in text (not color alone); success/failure is announced, and failure restores the prior image.
  • Remove is reversible via inline Undo (no confirm modal, no “bytes deleted” claim); it is a field-local affordance, not a global toast — ImageField requires no ToastProvider.

Form primitives

Foundational input layer. FormField owns the ARIA wiring — labels link via htmlFor, helper/error text via aria-describedby, invalid state via aria-invalid. The inputs read the context and stay simple at the call site.

One visual size for v1 (44px touch target on every interactive input). Density is tighter than typical SaaS marketing UI — operational forms scan top-to-bottom with clear rhythm.

FormField · FieldLabel · FieldDescription · FieldError

The unit of one labelled control. FormField generates stable IDs and exposes them through context; FieldLabel, FieldDescription, FieldError, and the inputs all read from it. Two layouts: stack (default — label above input) and inline (Checkbox / Switch).

Anatomy

A typical text field. Required marker on the label; helper text below; error reserved for validation.

Visible to participants in the catalog.

Optional marker

Mark optional fields explicitly when most fields are required. Use either required (*) or optional ((optional)) consistently within a form, not both.

Not shown to participants.

Invalid + error

Setting invalid on FormField shifts the input border to danger and pulls the error message into aria-describedby alongside the description.

Maximum number of participants who can enrol.

Capacity must be a positive whole number.

Long label wraps cleanly

Labels are not constrained to one line — the field stays operational with long, explicit copy.

The waitlist starts admitting participants automatically once a confirmed participant withdraws.

Narrow viewport

Fixed to 320px — the foundation operational width. Label and helper text wrap; input fills the column.

Shown in admin lists and on participant invitations.

Accessibility & responsive notes
  • FormField generates the input ID, description ID, and error ID and exposes them via context — the inputs and label components consume them automatically.
  • FieldLabel renders a real <label htmlFor>; clicking it focuses the input.
  • The input's aria-describedby always references the description ID and adds the error ID when invalid is true.
  • FieldError uses no role="alert" — validation errors travel with the input via aria-invalid + aria-describedby; the screen reader announces them on re-focus rather than interrupting the current read.
  • required and optional are mutually exclusive — the optional marker is suppressed when both are set.
  • Contrast — known deviation. Input borders use border-neutral-400 (≈ 2.45:1 against white) and placeholders use text-neutral-500 (≈ 4.57:1, meets WCAG 1.4.3 AA). Strict WCAG 2.2 SC 1.4.11 Non-text Contrast calls for 3:1 on UI-component identifying borders, which would push us to neutral-500 (≈ 4.6:1) — visually heavy on dense operational forms. We've logged this as a deliberate, documented deviation so it surfaces in the next audit; revisit during the Via UI/UX sync.

TextInput

Single-line input. Native type is honored — text, email, number, tel, url, password, date — so the browser keyboard and validation behave correctly per-platform.

States

Default · required · optional · disabled · read-only · invalid. All visually distinct without relying on color alone.

Default

Required

Optional

Disabled

Read-only

Invalid

Must be a positive whole number.

With helper text

Helper text sits below the input and is wired into aria-describedby. Use it for constraints (formats, character limits) — not for nice-to-have copy.

Participants can no longer submit applications after 23:59 in their local time on this date.

Long label

Multi-line labels stay readable. Avoid them when a short label + helper text would do.

Narrow viewport

320px column. Input fills width; label wraps.

Accessibility & responsive notes
  • One size: min-h-11 (44px touch target) at every breakpoint. Compact size variants are deferred until a real Phoenix workflow needs them.
  • Disabled state preserves the label in the accessibility tree; the input is removed from tab order and visually dimmed.
  • Read-only state keeps focus and selection — useful for displaying derived values that must be copyable but not editable (e.g., system-generated slugs).
  • aria-[invalid=true] Tailwind variant shifts the border to border-danger — driven by the FormField context.

PhoenixSelect

Phoenix's canonical dropdown — everywhere else in this file, and everywhere in Admin and Portal, a select control should be this, not a native <select>. A WAI-ARIA select-only combobox styled to match TextInput exactly (same border, surface, height, focus ring), because the browser's native option-list chrome doesn't follow the product's dark mode.

States

Default · disabled · invalid. Controlled only (value + onChange) — compose with FormField or pass label directly for a standalone aria-label.

Default

Disabled

Invalid

Accessibility & responsive notes
  • Keyboard: Enter/Space/Down opens the trigger; Up/Down moves the active option; Enter selects; Esc/Tab closes. Matches the ARIA APG "Select-Only Combobox" pattern exactly.
  • Originated in Activities admin forms and promoted to @viatrm/ui after 8 call sites across Activities, Settings, and Experiences forms had already adopted it independently — the de facto standard made official.
  • Do not reach for a native <select>, a hand-rolled dropdown, or a Popover-based single-select for this job. See the Browse filtering pattern below for the canonical way to compose several of these into a filter row.
  • An optional placeholder prop overrides the trigger's empty-state text (defaults to "Select…") — e.g. DropdownQuestion passes "Choose…" to match the Forms Studio widget Design.

Textarea

Multi-line input. Same border, focus, and state styling as TextInput. Vertical-only resize so users can grow the field for long content (advisor notes, submission review). rows controls the initial height.

States

Default · required · optional · disabled · read-only · invalid.

Default

Required

Optional

Disabled

Read-only

Invalid

Eligibility statement is required before the Experience can be published.

With helper text and larger rows

Use rows to give long-form fields room to start. Users can still drag the resize handle vertically.

Visible to all reviewers for this Requirement. Not shared with the participant.

Narrow viewport

320px column. Textarea fills width; resize handle still works.

Accessibility & responsive notes
  • Vertical-only resize (resize-y) — horizontal resize would break responsive columns.
  • min-h-24 (96px) keeps the input usable from first render even before the user resizes.
  • Read-only Textareas are the standard pattern for showing a Submission's prior content during review — selectable, copyable, but not editable.

RichText

The single read-only renderer for sanitized rich-text HTML — used by the Experience brochure fields and Activity descriptions so the admin preview and the participant view share one content path. Content is authored with the TipTap editor (Activities + Studio). RichText sanitizes on render against the shared allowlist (@viatrm/validation — bold, italic, links, lists, H2/H3, blockquote only), and the API sanitizes again on write. Inherits font size and color from the wrapper, so each field keeps its own typography via className.

Formatted content

Allowed marks render; the wrapper's className sets the base type scale.

Study in the heart of Rome with faculty-led seminars and immersive fieldwork.

Questions? Read the guide.

Legacy plain text (backward-compatible)

Values saved before rich text shipped have no tags — they render as text with line breaks preserved, exactly as before. No migration.

A plain paragraph. With a second line preserved.

Malicious HTML is stripped

Scripts, images, iframes, inline styles/classes/handlers, and unsafe links never render — even if they somehow reached storage.

Only this safe text survives.

bad link

Accessibility & responsive notes
  • Two sanitization passes: on API write (services) and on render (this component) — defense-in-depth for participant-facing, admin-authored HTML.
  • Allowlist mirrors the editor toolbar exactly: p / br / strong / em / h2 / h3 / ul / ol / li / blockquote / a. Links get rel="noopener noreferrer"; unsafe schemes are dropped.
  • Empty, null, or whitespace-only input renders nothing (matches the old value ? … : null pattern at each call site).

Checkbox

Native <input type="checkbox"> with accent-primary styling — fully accessible by default (keyboard, screen reader, magnifier, forced-colors). Always compose with FormField layout="inline" so the FieldLabel wraps the touch zone via htmlFor.

States

Default · required · disabled · invalid. Native checkboxes don't support read-only; use disabled instead.

Default

Anyone can view the Experience details, but only authorized participants can apply.

Required + checked

Enforced before participants can submit.

Disabled

Locked while the Session is in draft.

Invalid

You must agree before publishing.

Stack of preferences

A typical participant-preferences pattern: a column of checkboxes inside a Container.

Itinerary changes, deadline reminders, and travel advisories.

Includes your bio, photo, and emergency contact information.

Advisors can read but not comment on private journal entries.

Long label

Multi-line labels wrap; the checkbox stays aligned with the first line of text via mt-0.5.

The application cannot be re-opened after submission without an advisor's approval.

Narrow viewport

320px column. Checkbox + label row wraps cleanly; the touch zone stays large.

Participants cannot complete pre-departure without this.

Accessibility & responsive notes
  • Native <input type="checkbox"> — the most accessible primitive available. accent-primary themes the check fill without custom rendering.
  • Touch target: the visible checkbox is 20×20. The combined touch zone for toggling is met by FormField layout="inline" (min-h-11 row) plus the FieldLabel's htmlFor link — tapping anywhere on the label toggles the input.
  • Native HTML doesn't support read-only checkboxes. Use disabled when the value cannot change in the current context.
  • For an indeterminate checkbox (e.g., header of a partially-selected list), set the input's indeterminate property via a ref — not yet surfaced as a prop; deferred until a real table-selection pattern needs it.

Switch

Binary on/off control. Implemented as a native checkbox with role="switch" — modern screen readers announce it as a switch (on/off) rather than checked/unchecked. Use a Switch for instant-effect settings (toggle a feature); use a Checkbox for choices that are committed on form submit.

States

Default · on · disabled · disabled+on.

Off

When off, the catalog shows the Session but the apply button is disabled.

On

Send an in-app notification when a participant submits this Requirement.

Disabled (off)

Locked — requires Provider Portal Phase 2.

Disabled (on)

Set automatically when the Experience is published.

Settings group

Switches read densely in vertical stacks — the affordance signals an instant-effect setting, no save button needed.

Visible at /catalog. Off keeps the Session unlisted but still accessible by direct link to authorized participants.

When capacity is reached, additional applicants join a waitlist instead of being rejected.

Participants must pass eligibility before they can submit application materials.

Long label

Switch stays anchored top-left while the label wraps.

No effect on weekends or on advisor accounts that have email notifications disabled at the account level.

Narrow viewport

320px column. Switch + label remain side-by-side; label wraps below.

In-app + email when a country risk level changes.

Accessibility & responsive notes
  • Native <input type="checkbox" role="switch"> — keyboard activation via Space comes free; AT announces as a switch on / off.
  • The visual track and knob are aria-hidden — they sit behind the input via peer-checked: modifiers and don't intercept clicks.
  • Touch target: the switch visual is 24×44 (44 wide, 24 tall). The combined row in FormField layout="inline" (min-h-11) plus the htmlFor-linked FieldLabel gives the 44×44 effective touch zone per CLAUDE.md §8.1.
  • Switch vs Checkbox: switches signal instant effect; checkboxes signal "committed on submit." Don't mix them in the same form for the same kind of decision.
  • Motion: knob and track transitions respect prefers-reduced-motion.

Composition: Create Session

A realistic admin workflow composed from the existing layout primitives plus the new form primitives. PageHeader → SplitLayout → Section / Container / Stack → FormField + inputs. Form actions sit in a sticky footer-style row at the bottom of the form column.

Form questions (Forms M1.5)

One field-level widget per Forms question type — a step up from the raw primitives above. Each takes label / help / required and owns its own a11y wiring. Short text through Date additionally take value / onChange / error — a runtime/builder consumer never hand-wires FormField for the common case.

FileUploadQuestion and SignatureQuestion are the exception: Studio-only AUTHORING STUBS (workstream #3S) — a disabled, non-interactive "available soon" placeholder, never a real dropzone/file input or signature-capture pad, and never avalue/onChange. Real participant file upload / signature capture is a DEFERRED, escalation-gated surface per the ratified Governed-tier threat-model (CLAUDE.md §15 "Forms & the Governed tier"). Excludes image, video, and file (the presentational/media content kinds) — those remain a later, unbuilt workstream.

Not wired to any API and no builder/runtime shell yet — that's a later slice (M1.4). These are pure, controlled inputs today.

ShortTextQuestion

The short_text question type. Composes FormField + TextInput — single-line, value_type: text.

Default + error

Help text describes meaning; the error replaces it in aria-describedby priority the same way FormField does.

Default

As it appears on your passport.

Invalid

This field is required.

Accessibility & responsive notes
  • Same value shape as paragraph — they differ in constraint + widget only (storage-identity-reporting-decision.md §3.4).
  • Renders <label htmlFor> via FormField; the asterisk and aria-required come from required.

ParagraphQuestion

The paragraph question type. Composes FormField + Textarea — multi-line, same value_type: text as short_text.

Default

rows defaults to 4; grows via the native resize handle.

A few sentences is plenty.

With a word-limit hint

An optional maxWords prop renders an "N words maximum" hint (combined with any help text into one description). No Forms config wires this yet — component-level readiness only.

150 words maximum

QuestionFieldset

The shared <fieldset><legend> layout behind every GROUP-style question widget below (MultipleChoiceQuestion, CheckboxQuestion, RatingQuestion, FileUploadQuestion, SignatureQuestion) — the group counterpart to FormField's single-<label htmlFor> wiring. It owns the legend, the required marker, and help/error text wired via aria-describedby on the fieldset itself — announced once per group rather than once per option. It takes a render prop and is deliberately option-row-agnostic; every widget below supplies its own row visuals (radios, checkboxes, a disabled card). This section demos the primitive alone, with plain rows, so the disabled/read-only distinction below isn't tangled up with any one consumer's styling.

Required, with help text

The render prop hands back describedBy (for each option's aria-describedby) and idPrefix (for stable option ids) — the same two values MultipleChoiceQuestion/CheckboxQuestion thread into their own rows.

Preferred campus

Choose the campus you'd attend.

Default, disabled, and read-only

disabled dims the whole group (opacity on the fieldset, cascading to every descendant) and natively disables every control with no per-option wiring. readOnly disables the same native way — there's no native readonly for a radio/checkbox group — but skips the dim, so a submitted answer under review (admin's read-only Forms response drawer) stays at full contrast instead of looking unavailable.

Default

Preferred campus

Choose the campus you'd attend.

Disabled

Preferred campus

Read-only

Preferred campus
Accessibility & responsive notes
  • disabled sets the native disabled attribute on the <fieldset>, which cascades to every descendant control — no per-option threading required.
  • readOnly is a distinct, non-interactive review-of-an-answer mode from disabled — same native block on interaction, full contrast instead of the dim.
  • The required asterisk is visible text but aria-hidden — the group's accessible name stays exactly the label, never "label *".
  • Option-row visuals (radio/checkbox styling, ≥44px touch target, focus ring) are each consumer's own concern — see MultipleChoiceQuestion/CheckboxQuestion below for the real row treatment.

MultipleChoiceQuestion

The multiple_choice question type — single-select. value_type: single_option_ref; the answer stores the option id, never its label, so relabeling an option never rewrites history. A <fieldset><legend> groups native radios — the same pattern already used by the login role picker — rather than FormField's single-<label htmlFor> wiring, which fits one control, not a group.

Default + error

Radio rows meet the 44px touch target; the group's accessible name comes from the legend.

Default

Preferred campus

Invalid

Preferred campus

Choose one campus.

Accessibility & responsive notes
  • Uses <fieldset><legend>, not FormField — screen readers announce the group name and option count when focus enters any radio.
  • Help/error text is referenced via aria-describedby on the fieldset itself, so it's announced once per group, not once per option.

CheckboxQuestion

The checkbox question type — multi-select. value_type: multi_option_ref, modelled as one answer with N selected option ids. Composes the Checkbox primitive per option inside the same fieldset/legend group as MultipleChoiceQuestion. Not to be confused with the single Checkbox primitive above (a yes/no control) — this is a group of checkboxes answering one question.

Multi-select

Toggling an option adds/removes it from the value array; unrelated options are unaffected.

Dietary restrictions

Select all that apply — shared with housing and catering.

The dropdown question type — same value_type: single_option_ref shape as multiple_choice, different widget. Composes PhoenixSelect (CLAUDE.md §7.10) — never a native <select>.

Default

Controlled combobox inside FormField.

RatingQuestion

The rating question type — value_type: number, a numeric-scale variant. Two display variants, both a fieldset/legend group of native radios (min/max inclusive, defaults to 1–5): Stars (the default — a visually-hidden radio per star, filled 1..value, each with its own "N star(s)" accessible name) and Numbers, which keeps the radio control visible rather than hiding it behind a custom "button" skin — same rationale as Checkbox: the native control is accessible by default.

Stars (default) — with low/high captions

Optional lowLabel/highLabel captions sit under the scale.

How would you rate your orientation session?
PoorExcellent

Numbers

display="numbers" — the original numbered-box style.

How would you rate your orientation session?

0–10 (NPS-style) — wraps at narrow widths

min/max are configurable. The row wraps (flex-wrap) rather than scrolling, so an 11-point scale stays usable at 320px.

How likely are you to recommend this program to a friend?
Not at all likelyExtremely likely

DateQuestion

The date question type — value_type: date. Composes FormField + TextInput type="date" — the platform-native date picker, keyboard-operable and screen-reader-supported without a custom calendar widget.

Default

Optional min/max native bounds, e.g. to block dates outside a valid passport window.

Must be valid for at least 6 months after your return date.

FileUploadQuestion Authoring stub

The file_upload question type — value_type: asset_ref. Studio-only: a disabled, non-interactive "available soon" card via QuestionFieldset. Real participant upload is DEFERRED/escalation-gated (Governed-tier threat-model G-4, CLAUDE.md §15) — this component must never grow a value/onChange/upload prop.

Default

Required marker + help text both wire through QuestionFieldset exactly like the group widgets above; the card itself is inert.

Passport photo page

Participants will upload a file here.

Accessibility & responsive notes
  • Fieldset is natively disabled — perceivable to keyboard/AT as an inert group, not just visually dimmed.
  • No file input anywhere in the DOM — nothing to click, drag, or drop.

SignatureQuestion Authoring stub

The signature question type — value_type: signature_ref. Same Studio-only inert-card posture as FileUploadQuestion above. Real signature capture — and storing the drawn signature's content at all — is DEFERRED/escalation-gated (Governed-tier threat-model G-3: biometric-in-immutable-plane, Product ruling owed).

Form renderer (@viatrm/form-renderer)

The shared, placement→widget dispatch for a PublishedFormDocument — mirrors @viatrm/experience-brochure's <BrochureRenderer> contract: owns placement rendering + conditional visibility + the accent theme context; the consumer owns the page container, heading, and any editor/fill chrome. Form Studio's preview canvas is the first consumer (its Edit mode is unchanged, still opting into full per-placement control via renderPlacement); the participant fill surface (apps/portal) and Studio's own Participant-preview mode are the second, meeting CLAUDE.md §3.7's second-consumer promotion test.

When no renderPlacement is supplied (the DEFAULT — both demos below), placements fold into SECTION CARDS: everything before the first Section Heading renders in one card with no label above it; each Section Heading renders as a label above its own shared card, holding every placement up to the next Section Heading; a document with no Section Heading at all renders as a single card. A Form Heading, when present, never joins a section. A section with nothing visible left after conditional filtering (including an empty section — a heading immediately followed by another, or by nothing) hides entirely rather than showing an empty card.

Four render modes, chosen entirely by which props the caller passes: uncontrolled preview (Studio's "enabled but inert" mode — real interaction against local, uncommitted state), controlled (bound to values, calls onChange — the autosave wiring), disabled (bound to values but genuinely non-interactive, rendered dimmed — the participant fill surface's submitted-confirmation view), and read-only (same non-interactive binding, but at full contrast instead of dimmed — admin's Forms response drawer, so a reviewed answer stays legible).

Uncontrolled preview (Form Studio's mode)

No values/onChange passed — every widget is genuinely interactive against local, uncommitted state. applyConditionalVisibility={false} mirrors Studio's own posture: it never live-hides a question.

As it appears on your passport.

Travel details

Preferred campus

Only shown once "Rome" is selected above.

Disabled (the participant fill surface's mode)

Bound to saved values but read-only — nothing is editable yet (autosave is a later slice). Conditional visibility is ON by default: the follow-up question shows because the bound campus answer is 'rome'.

As it appears on your passport.

Travel details

Preferred campus

Only shown once "Rome" is selected above.

Read-only (admin's response review mode)

Genuinely non-interactive, like Disabled above — but each widget renders at full contrast instead of the dimmed disabled look (a11y contrast fix). Admin's Forms response drawer uses this mode; the unanswered 'Rome trip plans' question shows a muted 'Not answered' line instead of a blank box.

As it appears on your passport.

Travel details

Preferred campus

Not answered

Only shown once "Rome" is selected above.

Conditional visibility

Toggling the campus answer re-runs the shared evaluateConditional (@viatrm/validation) — the follow-up placement appears only once 'Rome' is chosen, matching the participant runtime's real behavior.

    Accessibility & responsive notes
    • Presentational/media content (Section Heading shown above, plus Paragraph Text / Divider / Image / Video / File Download) renders its REAL content — never a schema summary — via the same VideoEmbed/ResourceCard the participant-facing brochure uses.
    • file_upload/signature always render as the Studio-only AUTHORING STUBS shown above, in every mode — see FileUploadQuestion/SignatureQuestion's own entries.
    • The two demos above (Uncontrolled preview, Disabled) supply no renderPlacement, so they show the DEFAULT section-card layout: "Legal name" sits in the leading card above the "Travel details" label, which owns its own card holding "Preferred campus" and the conditional follow-up. The Conditional visibility demo below supplies its own renderPlacement instead (the same override Form Studio's Edit mode uses for its per-question selectable cards) — an explicit opt-out of the section-card grouping.

    Campaign email renderer (@viatrm/campaign-email)

    The shared, read-only render of a resolved CampaignEmailView — the same contract shape @viatrm/experience-brochure's <BrochureRenderer> established: the package owns the email DOCUMENT (masthead, subject, preview text, the ordered block body, footer), and the consumer owns the container, any device frame, the "Live preview" chrome, and every editor affordance.

    Two committed consumers, which is CLAUDE.md §3.7's second-consumer bar: the admin Campaign builder's live preview (today) and the send path (Campaigns slice 4), which must render the author's approved content rather than a second, independently-written version of it. The renderer takes a RESOLVED view rather than a CampaignDetail precisely so the package needs no data fetching and no tenant-scoping knowledge — a programs/events block stores bare ids, and turning one into a title is a permissioned read the renderer must never perform.

    Six block kinds, and deliberately no standalone image block: an author cannot drop an arbitrary picture into a message, because there is no publicly-servable asset URL to give one (only authenticated_cacheable assets are served, and an email client fetches images unauthenticated from outside the session — issue #542). Rich text goes through @viatrm/ui's <RichText>, which re-sanitizes on render — this package contains no dangerouslySetInnerHTML of its own.

    Email HTML is not web HTML, and the WHOLE document obeys that. The frame, the masthead, the subject treatment, every body block, the cards, and the footer are nested <table role="presentation">s and block elements carrying inline styles with literal hexes — no flexbox, no grid, no CSS custom properties, no @media, and no class names — because Outlook renders through Word and supports none of them. That is also why the portal's <ExperienceCard> is not reused here however similar the two look. The palette is transcribed from tokens.css's LIGHT theme, so the document renders fixed-light in both themes — that is what an email is, and a theme-following preview would misrepresent what the recipient receives. A card's cover image is resolved by the consumer, never by the renderer: only an absolute http(s) URL is loadable in an inbox, so a managed (uploaded) cover arrives as null and the card then renders no image slot at all — never a grey placeholder, which in an inbox reads as a broken image. When #542 lands, a managed cover resolves to a public URL and starts arriving in the same field with no change here.

    Three things the design draws that Outlook cannot render, recorded rather than papered over: the 600px column is a max-width (a width="600" attribute would force horizontal scroll at 320px, which §8.1 forbids), and Word ignores max-width — so Outlook reads the message full-width. The masthead's round brand dot and the button's filled pill both need border-radius, which Word also ignores — a square dot and an accent-coloured text link. A VML-conditional "bulletproof" button needs an HTML serializer to emit the conditional comment, which is the send path's job (slice 4), not this renderer's.

    Every block kind (desktop)

    Heading, rich text, the two-up Experience card grid (one with a cover image, one without — no placeholder block, just a tighter card), an Activities list drawn as rows with a calendar mark, a divider, and a button. The undated activity renders no date line at all rather than a 'Dates TBD' placeholder, and the unpublished one is marked in words — a recipient could not open it. 'Learn more →' is styled TEXT, not a link: there is no public marketplace, and the portal is behind auth, so a real href would send a student to a login wall.

    A brand-new campaign

    No subject and no blocks yet. The subject slot says 'No subject line yet' as an explicit placeholder rather than rendering an empty heading, and the empty-body copy is supplied by the CONSUMER — what to do next differs between the builder (which points at its own block picker) and the send path (which would never render an empty body at all).

    The chrome the Campaign builder's preview pane wraps the renderer in — a radiogroup, because these are two mutually exclusive readings of one thing. The toggle lives in the consumer, not the package.

    Accessibility & responsive notes
    • headingLevel (2 or 3) sets the level of the subject heading; block headings render one level below it. The renderer never assumes it owns the page's <h1> — a preview embedded in a builder must not compete with the page heading, and the demos above pass 3 because this page owns an h2.
    • The masthead's organization name is a <p>, not a heading: it is branding chrome and must not appear in a screen reader's heading outline. It comes from the Client's own displayName (§8.3's whitelabel surface) — never a Via brand string.
    • A button block renders as a real <a href> with rel="noopener noreferrer", because in a delivered email that is exactly what it is. A styled <span> would make the preview lie about what the recipient receives.
    • The footer's unsubscribe line is TEXT, not a link: no unsubscribe endpoint exists (consent and preferences are deferred wholesale), and a link that 404s is worse than a statement of intent. It becomes a real link when the preference centre does.
    • There is no metric, recipient, or delivery field anywhere in the component, and nowhere to put one: it describes a MESSAGE, never its outcome. A test asserts the rendered output matches none of delivered|opened|open rate|clicks|recipients.
    • smsSegmentStats() ships from the same package — the SMS bubble is consumer chrome (a handset draws a text natively; there is no document to render), but the GSM-7 segment arithmetic is shared so the count the author sees and the count the send path reports cannot diverge. It assumes GSM-7 and therefore UNDER-counts a message containing emoji or non-Latin script, which is documented as an approximate authoring hint rather than billing information.

    Data tables

    Native <table> semantics with opinionated dense defaults. Compose DataTable, TableHeader, TableBody, TableRow, and TableCell directly — no schema-driven column config, no plugin layer. Add a toolbar, filter bar, bulk-action bar, and pagination around the table as the workflow needs them.

    Density rhythm: px-3 py-2.5 per cell; divide-y rows; no vertical borders. Selected rows tint to bg-neutral-100; hover tints to bg-neutral-50. Mobile strategy: intentional horizontal scroll on the table container, plus low-priority columns hidden via hidden sm:table-cell / md: / lg:. For deeply mobile-critical lists, render a stacked Container list at narrow widths instead of the table — see the bottom of this section.

    DataTable · TableHeader · TableRow · TableCell

    Native semantics first. Header cells use scope="col"; cells inherit text-sm with neutral-700 body text; the scrollable container is the only wrapper DataTable adds.

    Defaults — Sessions roster

    A typical operational list. Columns wrap by content; long names truncate via the consumer's column width (or by adding the truncate prop to the cell).

    Accessibility & responsive notes
    • DataTable renders a real <table> inside an overflow-x-auto wrapper — the only intentional horizontal-scroll containment per CLAUDE.md §8.
    • Header cells default to scope="col"; pass scope="row" on the leftmost body cell to make long-row tables more navigable for screen readers.
    • Required ARIA: set aria-label or aria-labelledby on every DataTable. For the SR-only equivalent, pass srOnlyCaption.
    • Hover state is bg-neutral-50; selected is bg-neutral-100. These don't collide because a selected row stays at neutral-100 even while hovered — visually consistent.

    Selection · Indeterminate · BulkActionBar

    Selection is a composition of an existing primitive (Checkbox) inside the leftmost cell of each row plus a "select all" checkbox in the header. The header checkbox supports indeterminate when some rows are selected. The BulkActionBar appears between the toolbar and the table once at least one row is selected.

    Selectable rows with bulk actions

    Tick rows to surface the BulkActionBar. The header checkbox toggles between (none), (indeterminate when some), and (all).

    • The header checkbox carries aria-label="Select all…"; each row checkbox carries the row's noun ("Select Rome Study Abroad"). Without these labels, AT users hear only "checkbox."
    • The selected-row class is bg-neutral-100. Calm — no alarming highlight — and the checkbox state plus BulkActionBar carry the signal.
    • indeterminate on the header checkbox is the native DOM property, set via an effect inside Checkbox. The mixed state is announced by AT in modern browsers without any extra ARIA.
    • BulkActionBar renders nothing when count === 0 — no layout flicker.
    • Cross-page selection ("select all 184") is deferred until a real Phoenix workflow needs it.

    SortableHeader

    A <th> with a button inside. The button is the keyboard target; the <th> carries aria-sort (ascending / descending / none) so AT users can detect the sort direction without seeing the chevron.

    Two sortable columns

    Click a header to cycle asc → desc. Inactive columns show a subdued double-chevron; the active column shows a single chevron in the current direction.

    Accessibility & responsive notes
    • The sort cycle is consumer-defined — most tables alternate asc → desc; some include a third "unsorted" state. The primitive just renders whatever direction the consumer passes.
    • Keyboard: Tab to focus, Enter/Space to toggle. The button has a thick focus ring that sits inside the header background so it doesn't clip on dense tables.
    • Compose SortableHeader in the same <tr> as non-sortable TableHeadCells; they share alignment and padding.

    ActionsMenu

    The kebab-button popover used for per-row actions. Always provide a per-row accessible label ("Actions for {row name}") so AT users can disambiguate identical triggers across rows.

    Default — five items with a separator and a destructive action

    Activate with mouse or keyboard. Esc closes and returns focus to the trigger; outside click closes without focus return.

    Rome Study Abroad
    Accessibility & responsive notes
    • Trigger: aria-haspopup="menu" + aria-expanded. Menu container: role="menu"; items: role="menuitem".
    • Keyboard: Down on trigger opens + focuses first item. Up/Down inside cycle items. Esc closes and returns focus to trigger. Enter/Space activates the item and closes.
    • Touch target: the visible kebab is 36×36; an invisible before:-inset-1 pseudo-element extends the click zone to 44×44 to satisfy CLAUDE.md §8.1 on mobile.
    • Items pass index sequentially so the parent can roving-focus them. Without it, arrow-key navigation falls back to no-op.
    • Type-ahead search, submenus, and roving tabindex across multiple instances on the same page are deferred to a future generic Menu primitive.

    TableToolbar · TableSearch

    The toolbar slot above the table. Left cluster typically holds search and filter triggers; right cluster holds the primary action. Wraps below 640px so all controls stay reachable at 320px.

    Toolbar with live search

    Type to filter the rows below. Live filtering, no submit. The input is type=search so the browser's native clear (×) is available.

    • TableSearch is a real <input type="search"> — keyboard, screen-reader, browser clear button all work natively.
    • The toolbar's start / end slots are convenient defaults; pass children instead if you want full control of the row layout.
    • For dense workflows with many filter triggers (state, owner, date range), favour an "Add filter" button that opens a popover rather than crowding the toolbar with one button per dimension.

    FilterBar · FilterChip

    The row of active filters between the toolbar and the table. Each chip is one applied filter; clicking the chip removes the filter. The whole chip is the click target — there is no separate × tap zone.

    Active filters with remove and clear-all

    Click a chip to remove that one filter; Clear all removes everything. Filters wrap to multiple rows at narrow widths.

    Filters
    Accessibility & responsive notes
    • Each FilterChip is a single <button> with a 44×44 minimum touch zone via min-h-11 — strict compliance with CLAUDE.md §8.1 on mobile.
    • The chip's accessible name is auto-prefixed with "Remove filter" when children is a string; override via aria-label on the FilterChip for rich content.
    • For very dense lists with many filter dimensions, consider an inline filter-builder popover (deferred — not yet a primitive).

    Browse filtering (SearchField · PhoenixSelect · ClearFiltersButton)

    The canonical filtering row for browse/discovery surfaces — card grids the user scans and explores, as opposed to the dense data tables above. One wrapping row: SearchField, one PhoenixSelect per filter dimension, a ClearFiltersButton when anything's active, then Sort + a result count pushed right via ml-auto. Active filters (when tracked as removable, as opposed to the toggles shown here) surface below via FilterBar/FilterChip. This is the same row every browse page should use — Admin Activities' Browse view and Portal's Experiences marketplace both compose it this way.

    Search, filters, clear, sort, and count in one row

    Type in the search box or pick a filter to see Clear filters appear. Wraps at narrow widths rather than scrolling horizontally.

    12 experiences
    Accessibility & responsive notes
    • Controls stay quiet on purpose — no per-filter icons, no pill-shaped inputs. The cards below this row are the surface's hero; the toolbar should fade into the background.
    • Per-dimension filters render conditionally (only when more than one distinct value exists in the current data) rather than always showing every possible filter.
    • Layout wraps (flex-wrap) rather than scrolling horizontally — a horizontally-scrolling filter row has been observed to leak into document.documentElement.scrollWidth when nested inside SidebarLayout, causing page-level horizontal scroll at narrow viewports.
    • Do not invent a second version of this row with different radii, spacing, or a Popover-based filter builder for a browse/card surface — that's the pattern for dense data tables (see FilterBar above), not discovery pages.

    Pagination

    Operational prev/next pattern with a position indicator ("Showing 1–25 of 184"). Page-number lists are deferred until a real Phoenix workflow needs them (deep links, saved views).

    Prev/Next with position indicator

    Click Next/Previous to page through. Buttons disable at the edges of the range.

    • Wrapped in a <nav aria-label="Pagination"> so AT users can jump to it via landmark navigation.
    • Buttons use min-h-11 — full 44×44 touch target on mobile.
    • Page-size selectors, jump-to-page input, and page-number ranges are deferred. The current API is intentionally narrow so the operational workflow drives expansion later.

    EmptyState · LoadingState

    Empty states reuse the existing EmptyState primitive inside a single <td colSpan> row. Loading states render skeleton bars in place of cell content via LoadingRow, with aria-busy="true" on the DataTable so AT users know the data is refreshing.

    Empty — no rows yet

    Use the existing EmptyState primitive inside a colSpan row. Title states what's empty; description offers the next step.

    SessionTermStatus

    Loading — skeleton rows

    The DataTable carries aria-busy=true while LoadingRow placeholders render. The bars are aria-hidden — the busy attribute is the AT announcement.

    SessionTermEnrolledStatus

    LoadingState — single bar

    The atomic placeholder. Use directly inside any cell, in cards, in form previews, etc.

    Accessibility & responsive notes
    • Empty rows render inside the table's structural <tbody> so they share the header's column context — no special "empty" container needed.
    • The skeleton bars are aria-hidden. The single ATR announcement comes from the table's aria-busy="true" while loading.
    • Animations honor prefers-reduced-motion — the pulse stops when the user requests reduced motion.

    Responsive · narrow · stacked alternative

    At 320px, the table's scrollable container keeps it usable as a horizontal-scroll surface. For lists that are mobile-critical (participant's own dashboard, traveler portal), render a stacked Container list at narrow widths instead. Same data, different affordance.

    Column priority — hide on narrow widths

    The Experiences composition below hides Type at <md, Owner at <sm, Sessions at <md, Updated at <lg via hidden sm:table-cell etc. The Name + Status + Actions trio stays at 320px.

    • Default mobile pattern: keep the DataTable, hide low-priority columns via hidden sm:table-cell / md:table-cell / lg:table-cell on both the matching TableHeadCell and TableCell.
    • For lists that are primarily consumed on mobile (e.g., the traveler portal's requirements list), render a stacked Container list instead of a table at narrow widths. The DataTable is the desktop-first surface; stacked lists are the mobile-first surface.
    • When hiding a column, hide the matching header cell too — otherwise the column count mismatches and skews colspan-based empty / loading rows.

    • Toolbar, FilterBar, BulkActionBar, DataTable, and Pagination all sit inside a single Container variant="flush" padding="none" — each piece carries its own bottom or top border, so they connect visually without double-stacked borders.
    • The Name column is a link (<a href>). Rows are not themselves clickable — the explicit link target is more accessible and avoids conflicting with the checkbox / kebab inside the row.
    • Selection persists across pagination changes in this demo's state. For real workflows, decide whether selection should clear on filter or page change.

    Composition: Submission review queue

    The reviewer's daily working surface. Same primitives, different shape — a single status filter is pre-applied; bulk actions are approve / request changes / assign reviewer; the "all caught up" empty state replaces the row list when no rows match.

    • The status column communicates lifecycle via Badge tone+dot — neutral for Withdrawn, info for Pending / Under review, warning for Needs changes, success for Approved.
    • The Reviewer column shows "Unassigned" in a softer neutral colour rather than empty — the gap is operationally meaningful (a reviewer can act on it).
    • Per-row actions are tailored to the review workflow: Open review, Approve, Request changes, Reassign. Bulk actions mirror the most common review operations.

    Surface hierarchy

    Six layers from page background to critical attention. Each layer documents the shadows, borders, backdrops, z-index, and interaction ownership it carries. Picking the right surface is what keeps the platform calm — every primitive below points to one of these surfaces.

    Z-index philosophy: we use Tailwind's preset z-30 / z-40 / z-50 rungs for non-modal overlays. Modals are native <dialog> elements that participate in the browser's top layer and sit above every z-index — no arbitrary z-index values anywhere.

    Overlays

    Seven primitives that map onto Surfaces 3, 4, and 5. Modals (Dialog, Drawer, CommandPalette) use the native <dialog> element so the browser owns focus trap, Esc, top-layer stacking, and focus return. Non-modal surfaces (DropdownMenu, Popover, Tooltip) are controlled-state primitives with outside-click + Esc dismissal. Toast lives between them — non-blocking, but stacked above Surface 3 so it remains visible alongside ephemeral menus.

    Motion is restrained: backdrop fade for modals, subtle slide for Drawer and Toast. Every animation honors prefers-reduced-motion; the CSS lives in packages/ui/src/styles/overlays.css.

    Dialog

    Surface 4. Modal blocking dialog built on the native <dialog> element. The browser handles focus trap, Esc-to-close, focus return, and inert background. Backdrop click closes via the click-on-dialog-element pattern. Use for decisions that must be answered before continuing — confirmations, short forms, important questions.

    Default — Save changes?

    A typical operational confirmation. Title + description + footer with Cancel + primary. Tab cycles inside; Esc closes; focus returns to the trigger when closed.

    Save changes?

    You've made unsaved changes to this Session. Save them before continuing?

    Destructive variant — Surface 5

    Same Surface 4 substrate; the danger lives on the primary action (Button variant=destructive). The dialog body stays neutral so the warning sits where the user will click.

    Accessibility & responsive notes
    • Focus trap is the browser's. Tab and Shift+Tab cycle inside;Esc closes and fires the native close event which we wire to onClose.
    • Backdrop click closes by checking e.target === dialog in the onClick. Clicking inside the dialog body never closes by accident.
    • Initial focus goes to the first focusable element inside the dialog. Add autoFocus to a specific element to steer it (e.g., the Cancel button for destructive dialogs).
    • No enter / exit motion on the dialog body. The backdrop fades in via @starting-style; reduced-motion users get instant.
    • Sizes: xs / sm / md (default) / lg / xl. The dialog max-height is 85vh; longer body content scrolls inside.

    Drawer

    Surface 4. Same native <dialog> foundation as Dialog, anchored to the right (or left) viewport edge. Use a Drawer when the user needs to inspect or edit something without losing context — the Submission review queue + its detail view is the canonical case.

    Participant detail drawer

    Status, contact, requirement checklist, advisor notes. Footer holds Close + primary. Resize the viewport below 640px to see how it collapses to full-width on mobile.

    Advisor notes

    Accessibility & responsive notes
    • Slide-in motion is 180ms ease-out via @starting-style. Honors prefers-reduced-motion — reduced-motion users get an instant appearance.
    • Width: sm / md (default) / lg / xl — caps the drawer width but w-full on narrow viewports means the drawer fills the screen at 320px.
    • DOM is rendered into the native top layer — sits above every z-index without arbitrary values.
    • Focus trap + focus return are handled by the browser via showModal() + the dialog's native close event.
    • Backdrop dismissal fires only when the press and release both land on the backdrop — a press that begins inside the panel (text-selection drag, a native <select>/date popup whose option-click retargets to the dialog) does not close the drawer.
    • Right is the default anchor (matches Western reading direction for "more detail"). Pass side="left" when the drawer is conceptually navigation rather than detail.

    Surface 3. Labelled menu button — for toolbar menus, view-options, bulk-action groupings. Pair with ActionsMenu when you need a kebab affordance (row-level actions), and with Popover when the content is richer than a list of items.

    Two menus — left-aligned and right-aligned

    The trigger is a built-in Button; the menu opens below. Tab from a menu item closes the menu and moves focus to the next focusable element on the page.

    Accessibility & responsive notes
    • ARIA: trigger gets aria-haspopup="menu" + aria-expanded; menu is role="menu"; items are role="menuitem".
    • Keyboard: / Enter / Space on trigger opens + focuses first; opens + focuses last; / cycle inside; Home/End jump to first/last; Esc closes + returns focus to trigger; Tab closes + lets focus flow naturally.
    • Pass index sequentially on items so the parent can roving-focus them — without it, arrow-key navigation is a no-op.
    • Type-ahead, submenus, and roving focus across multiple menus on a page are deferred to a future generic Menu primitive.

    Popover

    Surface 3. Non-modal floating surface for richer content — filter builders, inline edits, picker-style choices. For action lists prefer DropdownMenu; for ephemeral hints prefer Tooltip.

    Filter popover with checkboxes

    The trigger is the consumer's element (typically a Button). Popover clones it to attach onClick + ARIA. Esc closes; outside click closes; focus stays where the user put it. The panel below sits inside an overflow-hidden frame yet is not clipped — it renders in a portal.

    Accessibility & responsive notes
    • Trigger receives onClick, aria-haspopup, aria-expanded, and aria-controls via cloneElement.
    • Content carries role="dialog" + aria-modal="false" with an aria-label from the required label prop — focus is not trapped, and Tab can leave the popover (which closes it).
    • Use the initialFocusRef prop when the popover contains a form (e.g., focus the first input on open).
    • The panel renders in a portal to document.body with position: fixed anchored to the trigger, so it is never clipped by an ancestor's overflow (a SplitView pane, a scroll container). Position recomputes on scroll/resize while open.

    Tooltip

    Surface 3. Ephemeral hint that appears on hover and on focus — CLAUDE.md §8 forbids hover-only reveals. Use Tooltip only for short, non-essential clarification; never put critical information here.

    Inline tooltips on small actions

    Hover over each button to see the tip. Tab through them to verify the same tip appears on focus — that's the test for the CLAUDE.md hover-only rule.

    Accessibility & responsive notes
    • Trigger receives aria-describedby while the tooltip is open. Closed tooltips don't leave a dangling ID on the trigger.
    • Tooltip body has role="tooltip" and is pointer-events: none — there's no way to focus a tooltip or click anything inside it.
    • Never use Tooltip for content that the user needs to act on. The trigger must always carry its own visible label (or aria-label for icon-only buttons) — the tooltip supplements, never replaces.
    • No reveal delay in v1 — instant on hover/focus. Repositioning (flip / shift near viewport edges) is deferred until a real Phoenix workflow needs it.

    Toast

    Surface 3 (z-50). Transient confirmation anchored to the bottom-right of the viewport. Wrap your app shell in <ToastProvider> and call useToast().push(...) from anywhere downstream.

    Four tones + an actionable toast

    Each button triggers a toast. Danger uses role=alert (assertive). Other tones use role=status (polite). Hover or focus a toast to pause its auto-dismiss.

    Accessibility & responsive notes
    • Region: <div role="region" aria-label="Notifications"> at the bottom-right. AT users can navigate to it via the landmarks list.
    • Per-toast: role="status" + aria-live="polite" for neutral / success / info / warning; role="alert" + aria-live="assertive" for danger.
    • Auto-dismiss: 5000ms default; duration=0 for persistent (user must dismiss). Hover or focus pauses the timer.
    • Limit: limit=4 by default — older toasts drop off as new ones arrive. No queue overflow indicator (deferred).
    • Enter motion: via-toast-enter keyframe — 150ms slide-up + fade. Reduced-motion users get an instant appearance.
    • Toasts use z-50 — sit above other Surface 3 overlays. Modals (top layer) still sit above toasts; that's acceptable because most operational toasts arrive after a modal closes.

    CommandPalette

    Surface 4. Keyboard-first quick launcher — minimal v1. Substring search, grouped listing, arrow-key navigation, Enter to activate. Open with Cmd/Ctrl+K via the useCommandShortcut hook in your app shell.

    Default — Create / Navigate / Bulk / Account

    Type to filter, ↑/↓ to navigate, Enter to activate, Esc to close. The dialog focuses the search input automatically on open.

    In production, also wire Cmd/Ctrl+K via useCommandShortcut(() => setOpen(true)) in the app shell.

    Accessibility & responsive notes
    • Same native <dialog> foundation as Dialog — focus trap + Esc + top layer are all browser-owned.
    • Search input carries aria-controls + aria-activedescendant; items are role="option" with aria-selected on the active row.
    • Substring matching only in v1. Fuzzy / scored matching, async / debounced search, per-command shortcuts, and recently-used boosting are deferred.
    • Wire the global shortcut via useCommandShortcut(() => setOpen(true)) in the app shell — opt-in, not auto-installed.
    • Mobile: works exactly like Dialog — full-width below 640px, full focus management. The shortcut is only visible to keyboard users on desktop.

    Composition: Experience management workflow

    Row ActionsMenu → destructive Dialog (Surface 5) → success Toast with Undo. The whole flow stays in one keyboard journey: Tab to the row, Enter on the kebab, ↓ to Archive…, Enter to open the confirmation, Tab to Archive, Enter to confirm. Focus returns to the row when the toast appears.

    Archive

    Accessibility & responsive notes
    • The Dialog uses variant="destructive" on the primary action — that's the Surface 5 signal. The dialog body itself stays neutral.
    • Toast tone is success (the action completed) with an Undo action so the operator can recover from a mis-click within the auto-dismiss window.
    • Focus return: when the Dialog closes (Esc, Cancel, or Archive), the browser returns focus to the row's ActionsMenu trigger automatically.

    Composition: Submission review workflow

    Filter Popover (Surface 3) → click a row → Drawer (Surface 4) with contextual actions (Approve / Request changes / Close). Approve fires a success Toast; Request changes fires a warning. The Drawer keeps the queue in view on desktop, full-screens on mobile.

    Accessibility & responsive notes
    • The status Popover holds Checkboxes the user can toggle without leaving the queue context. Esc closes the popover; the underlying queue stays interactive.
    • The Drawer is anchored right. Approve / Request changes fire Toast and close the Drawer; Close exits without changes. Tooltip on "Take queue" clarifies the bulk action without crowding the toolbar copy.
    • On mobile, the Drawer fills the viewport and the row content scrolls underneath when the Drawer is closed — no horizontal scroll required because low-priority columns (Requirement) are hidden below md.

    Worklist primitives

    Foundational primitives for the canonical Worklist archetype. These power Engagement first and every future Worklist (Inbox, Submissions, Risk). The architecture lives in docs/architecture/worklist-implementation.md; the decision notes for each primitive live alongside in docs/architecture/notes/.

    Phase 0 is complete: all three foundational primitives — KeyboardScope, SplitView, and WorklistTable — are shipped. Phase 1 composes them into the Worklist shell + Inspector + workspace state hooks.

    KeyboardScope + KeyboardCheatsheet

    Stack-based keyboard shortcut system. Wrap the app once in <KeyboardScopeProvider>, then mount <KeyboardScope> wherever a workspace, row, or overlay needs its own keys. The deepest scope in the render tree wins for nested cases; siblings at the same depth resolve by mount order — so opening a modal automatically intercepts shared keys without explicit wiring. Drop a single <KeyboardCheatsheet /> nearby and ? becomes a self-documenting help surface.

    Keyboard shortcuts

    Press ? to open the cheatsheet. Try j / k, the g e sequence, or ⌘K.

    Mount a row scope to see stacking in action.

    Recently fired

    No shortcuts fired yet.

    Try this

    · Press j with row focus off vs on — different actions fire.

    · Press g alone — nothing happens. Then e within a second — sequence fires.

    · Click in the search box below, then press j — nothing fires (input has focus). Then press ⌘K — still fires (allowInInput).

    SplitView

    Resizable two-pane layout with three modes (split, primary-only, secondary-only). Slot-based — pass <SplitView.Primary> and <SplitView.Secondary> as direct children. Mode and ratio are controlled-or-uncontrolled; persistence is the consumer's responsibility (a server-backed user-preferences slice lands in Phase 2 of the Worklist plan). The drag mechanics and ARIA separator come from react-resizable-panels; the snap/reset keybindings (Enter, Esc, Home, End) and the mode wrapping are ours.

    ratio: 40%

    Drag the divider to resize. With the divider focused, press / for arrow-key resize, Enter to cycle snap points, Esc to reset, and Home / End to snap to min / max.

    Primary

    In the Worklist, this is the list pane.

    Secondary

    In the Worklist, this is the inspector.

    Try this

    · Switch modes — the ratio is preserved across toggles, so going back to Split restores your last drag position.

    · Tab to the divider, then press Enter repeatedly to cycle through 5 snap points.

    · Try Esc anywhere on the divider — ratio resets to defaultRatio (40%).

    WorklistTable

    Virtualized ARIA grid for high-frequency operational lists. Built as a div-based role="grid" because virtualizing native <tr> breaks the layout flow that screen readers expect; the WAI-ARIA grid pattern is the accepted accessible alternative for this case. Fully controlled — focus, selection, sort, and density flow from props; the table doesn't own workspace state and doesn't register global keyboard listeners. Wire j / k / x / etc. via a <KeyboardScope> at the consumer, and call the table's imperative scrollToRow(id) when the focused row leaves the viewport.

    Keyboard shortcuts

    Density:1,500 rows · 0 selected

    Click the grid, then press j / k to move focus, x to toggle selection on the focused row, Esc to clear all selection, ? for the cheatsheet. Click any column header to sort.

    #

    Try this

    · 1,500 rows are rendered — DevTools will show only ~30 in the DOM at any time.

    · Switch density — virtualizer remeasures and the visible window adjusts.

    · Hold j — the grid scrolls to keep the focused row in view (only when off-screen).

    · Click a column header twice to flip direction; aria-sort updates accordingly.

    Empty state

    When items=[] and !isLoading, the body renders the emptyState slot — the header row stays so the column structure remains visible. Use a domain-aware empty state (EmptyState compositions live in @viatrm/ui).

    Title
    Category

    No items match

    Try a broader filter or clear the search to see the full list.

    Loading state

    When isLoading is true, aria-busy is set on the grid and loadingRowCount skeleton rows render in the body (default 8). The header is unchanged so the user keeps their column context.

    Operational awareness

    The Mission Control Home leads with attention, not records. Severity drives weight and the eyebrow word; signal is never color-only (the severity word and “Impact” text carry it). Chrome stays calm — color is spent only on meaning.

    ConsequenceCard — hero emphasis (the lead concern)

    Filled, prominent. One per severity. The action is the single interactive element.

    OverviewBackground — atmosphere by tone

    The recessive atmospheric layer behind the Home. Shown here are the gradient fallbacks (calm / active / critical) used until art-directed photographs are configured; a scrim keeps content AA over any image. Decorative, static, never competes with content.

    StatusCard — Phoenix status card

    Vertical status card with a spine, origin dot, and atmospheric gradient. Color is tone-mapped to danger / warning / info / neutral — but the signal is always carried in pillLabel and statusText too (color is never the sole indicator). Cards with a count of 0 receive active=false — muted opacity, no tone color. First implementation: Activities Needs Attention.

    Active state — four tones

    Inactive state — count zero

    Studio preview controls

    Device-size + light/dark preview frame for a live content-preview canvas — apps/admin/src/components/studio/preview-controls.tsx. First built for the Experience (Brochure) Studio; Form Studio is the second consumer, promoted per CLAUDE.md §3.7 rather than forked. An admin-local, cross-feature Studio primitive (not @viatrm/ui), included here because it is interactive and now shared by two Studios.

    DeviceToggle + PreviewThemeToggle

    Desktop is fluid; Tablet/Mobile frame the canvas to a fixed max-width (DEVICE_W). The theme toggle re-resolves every --color-* token inside the framed canvas via a nested data-theme island, independent of this page's own theme or the Studio chrome's theme.

    Preview canvas

    This box re-resolves every token-based class (bg-surface, text-fg, border-border, …) to light mode, independent of the styleguide page's own theme, and is capped at 100% wide for the desktop device.

    Accessibility & responsive notes
    • Both toggles are a labelled role="group" of aria-pressed buttons — Tab moves between options, Enter/Space selects. No native <select>, no color-only signal (the pressed option gets a filled background, not just a color change).
    • Each button is a 32px hit target inside a padded group — below the 44px touch-target guidance on its own, but the group as a whole sits in a toolbar cluster meant for precise pointer/keyboard use, matching the Brochure Studio's existing toolbar density; the surrounding toolbar row keeps a comfortable overall tap area.
    • usePersistedPreviewTheme(storageKey) hydrates from localStorage after mount (never blocks first paint on a synchronous read) and persists on change — each Studio passes its own storage key so Form Studio and the Brochure Studio don't clobber each other's preference.
