Don't: Sample operations labelled as a client's live data
Authored by imagery.tsRule illustration; not an executed check. imagery / imagery.real
Caption on a tour screenshot: "A client running its live operations."
Actual source: the read-only product tour with sample records.Don't: A stock mock-up replaces a captured screen
Authored by imagery.tsRule illustration; not an executed check. imagery / imagery.real
A stock dashboard image is labelled "Loom operations screen" without a product-tour source or capture.
The decorative mock-up is substituted for the actual working UI.Rules
| Rule | Why | Check |
|---|---|---|
| Every screen is captured from the read-only tour and captioned as real screen, sample records. | Truthfulness (AGR-0001). | Automated: npm run site:screens and the product-screen caption |
API
No props.
Contract details
The full contract: identity, anatomy, variants, states, tokens, layout, motion, accessibility, content, tests
Identity
| Aspect | Value |
|---|---|
| Id | imagery |
| Layer | Foundations |
| Category | foundation |
| Owner | Site system lead |
| Status | stable |
| Version | 1.0.0 |
| Source | apps/showcase/site/system/foundations/imagery.ts (private repository; the contract and the render function are this one module) |
| Version | Date | Change |
|---|---|---|
| 1.0.0 | 2026-10-26 | Imagery as one module: its markup moved out of the page builder (scripts/site) into the system. |
Use when
- Product screens on operations and role pages. Why: Real screens prove the product exists.
Do not use when
- Stock photography or generated people. Why: Invented imagery undermines a site whose argument is evidence.
Anatomy
| Part | What it is |
|---|---|
| screens | apps/showcase/public/product/img/ops/*.webp (npm run site:screens) |
| og | Open Graph images drawn from the brand (scripts/site/brand-images.ts) |
Made of: nothing (a base element).
Used in: pages directly.
Variants
| Variant | When | Why |
|---|---|---|
| light and dark | Every page, following the reader's setting. | The same roles resolve to light or dark values, so no element chooses its own. |
States
| State | Rendered or not applicable |
|---|---|
| default | The specimen. |
| hover | Not applicable: A foundation is not interactive. |
| focus-visible | Not applicable: Not focusable. |
| active | Not applicable: Not interactive. |
| disabled | Not applicable: Nothing to disable. |
| loading | Not applicable: Values are built into the stylesheet. |
| empty | Not applicable: The build fails if a value is missing. |
| error | Not applicable: Unresolved values fail the brand gate, not the reader. |
| current | Not applicable: No current item. |
| visited | Not applicable: Not a link. |
| expanded | Not applicable: Does not open. |
Tokens
| Part | Token |
|---|---|
| screen.border | --rule-hair --line-strong |
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 | Not applicable: a foundation has no box of its own. |
| external | Not applicable. |
| rhythm | Applies to every element that reads it. |
Motion
| Aspect | Value |
|---|---|
| None | A foundation does not move. |
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 | Not rendered on the site; its specimen in the Library is a list |
| name | The foundation's name |
| keyboard | Not interactive. |
| focus | Not focusable. |
| screenReader | The specimen is a plain list of names and values. |
| contrast | Every text and ground pair in the palette is checked (check-brand). |
| target | Not a target. |
Content
| Slot | Length | Voice |
|---|---|---|
| screen caption and provenance (ProductScreen / screenShot) | ProductScreen declares two sentences; the native renderer owns its source and captured-date suffix | Say what the real screen shows and that the records are sample records. Preserve the actual tour source and captured date when available; do not invent a capture date. |
| image alternative (screenShot data) | The actual screen title and caption; no independent foundation prop | Describe the screen's content, not a device mock-up or a fictional client result. Keep the sample-data disclosure in the same view. |
Good: “Real screen, sample records (ProductScreen's native provenance tag)” · “Open the read-only tour (screenShot's source link)”
Bad: “Mock-up (ProductScreen's rejected description of a real capture)” · “A client's live operations (unsupported claim for tour sample records)”
Japanese: Use ProductScreen's existing Japanese caption path where provided; scripts/site/visuals.ts retains English fallback for screens without SCREENS_JA entries. Japanese captions explicitly identify the English UI and sample records. This foundation neither translates the captured UI nor completes native Japanese review.
Icons and illustrations
None: this element uses no icon or illustration of its own.
Decisions and exceptions
- None.
Usage
118 owned-class occurrences in built pages plus metadata-token references in built CSS (measured by npm run site:system).
No application mechanism is declared.
Current check result: not assessed by this report. Declarations and source-file presence do not establish executed enforcement or accepted coverage.
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.
