Rules
| Rule | Why | Check |
|---|---|---|
| A task body holds one task. | One task in front of the reader is what makes a three-minute check finish. | Review: Site system lead |
API
| Prop | Type | Required | Default | What it does |
|---|---|---|---|---|
cls | string | Yes | Layout class: is-task (narrow), contact-grid (two columns), prose (a notice). | |
html | html | Yes | The task. |
Contract details
The full contract: identity, anatomy, variants, states, tokens, layout, motion, accessibility, content, tests
Identity
| Aspect | Value |
|---|---|
| Id | task-body |
| Layer | Templates |
| Category | section |
| Owner | Site system lead |
| Status | stable |
| Version | 1.0.0 |
| Source | apps/showcase/site/system/templates/task-body.ts (private repository; the contract and the render function are this one module) |
| Version | Date | Change |
|---|---|---|
| 1.0.0 | 2026-10-26 | Task body as one module: its markup moved out of the page builder (scripts/site) into the system. |
Use when
- Inside every Task page's main. Why: One column keeps the task in front of the reader.
Do not use when
- On content pages. Why: They use the Page body.
Anatomy
| Part | What it is |
|---|---|
| root | div.wrap.task-body with the layout class (is-task, contact-grid, prose) |
| inside | The app organism or the notice |
Made of: contact-form, health-check, survey.
Used in: task-page, page-apps.
Variants
| Variant | When | Why |
|---|---|---|
| is-task | The health check and survey. | A narrow column for questions. |
| contact-grid | The contact form. | The promise beside the form. |
| prose | Privacy notices. | Reading width. |
States
| State | Rendered or not applicable |
|---|---|
| default | default |
| hover | Not applicable: The task body is not interactive, so it has no hover state. |
| focus-visible | Not applicable: The task body does not take focus; links and buttons inside it carry their own focus ring. |
| active | Not applicable: The task body cannot be pressed. |
| disabled | Not applicable: The task body has nothing to disable. |
| loading | Not applicable: The task body is rendered at build time and is complete when the page loads. |
| empty | Not applicable: The task body is not rendered without content; the builder skips it. |
| error | Not applicable: The task body shows no data that can fail. |
| current | Not applicable: The task body has no current item. |
| visited | Not applicable: The task body is not a link. |
| expanded | Not applicable: The task body does not open or close. |
Tokens
| Part | Token |
|---|---|
| root.width | --w-text (is-task, prose) |
Layout
| Aspect | Value |
|---|---|
| breakpoints | Required review at 390, 768, 1024 and 1440 px; execution is not implied by this declaration; columns stack under 768 px; the wrap keeps a 16 px gutter on phones. |
| wrapping | Text wraps; nothing scrolls sideways. |
| textExpansion | Japanese runs 20 to 40% longer; headings break between phrases (jaBreaks) and blocks grow downwards. |
Spacing and rhythm
| Aspect | Value |
|---|---|
| internal | One padding: --space-section-sm (D-SITE-005). |
| external | Inside main. |
| rhythm | Header, task, footer. |
Motion
| Aspect | Value |
|---|---|
| None | No intrinsic element animation. The optional claude-entrance consumer profile may translate below-fold structure once (20px, --dur-weave, --ease-enter, --stagger); reduced motion disables it. This preserved baseline entrance is separate from element playback. |
Runtime and reuse
Render-only element; mount any registered child enhancements separately. Preserve required Site CSS, fonts, responsive and locale rules from nativeElement.
Accessibility passport
| Aspect | Value |
|---|---|
| role | region (section) named by its heading |
| name | Its h2, by aria-labelledby |
| keyboard | Links and buttons inside, in reading order. |
| focus | The --focus ring on every link and button inside. |
| screenReader | Read in source order; decorative weaving is aria-hidden. |
| contrast | Ink on cotton 14:1; text on every dye field 4.5:1 or better (checked by check-brand). |
| target | Links and buttons are 44 px tall. |
Content
| Slot | Length | Voice |
|---|---|---|
| html | One registered task app/form or one privacy notice; do not combine unrelated tasks. | Keep the task’s existing labels, heading structure and readable static fallback; the task organism owns its content. |
Good: “One health check or survey in the is-task column.” · “One privacy notice in the prose column.”
Bad: “Two unrelated forms in one task body.” · “A task with no selected layout column.”
Japanese: The task organism owns its translated labels, language controls and pending native-review note. Privacy content retains its source document language; English fallback text must remain identified as English.
Icons and illustrations
None: this element uses no icon or illustration of its own.
Decisions and exceptions
- None.
Usage
7 uses across the built pages (measured by npm run site:system).
Tests
| Aspect | Value |
|---|---|
| unit | tests/unit/site-system.test.ts: renders every do and don't example through the registry and checks the classes it owns |
| visual | Not yet: there are no screenshot baselines; the Library page is checked for sideways scroll at 1440 px by tests/site/system.spec.ts |
| a11y | tests/site/system.spec.ts: axe (0 serious or critical) on the element's Library page in light and dark |
| parity | scripts/site/system/check.ts: Library examples are rendered by the same render function the site imports |
Figma
not-yet: The Loom Site Figma library is the last stage of the plan; this element is not mapped yet.
