Rules
| Rule | Why | Check |
|---|---|---|
| The flows and layers tree is drawn from Loom's flow and layer records (scripts/site/interactives/flows.ts) at build time. | A figure read from the real records cannot drift from them. | Automated: npm run site:build (reads the data; fails if it is missing) |
| Each step starts with a verb. | Steps are actions the reader's team takes. | Review: Content owner |
API
| Prop | Type | Required | Default | What it does |
|---|---|---|---|---|
lang | en | ja | No | "en" | Interface language. |
kind | transform | creation | layers | Yes | Which flow. |
Contract details
The full contract: identity, anatomy, variants, states, tokens, layout, motion, accessibility, content, tests
Identity
| Aspect | Value |
|---|---|
| Id | flow-layers |
| Layer | Organisms |
| Category | diagram |
| Owner | Site system lead |
| Status | stable |
| Version | 1.0.0 |
| Source | apps/showcase/site/system/organisms/flow-layers.ts (private repository; the contract and the render function are this one module) |
| Version | Date | Change |
|---|---|---|
| 1.0.0 | 2026-10-26 | Flows and layers tree, drawn at build time from Loom's flow and layer records (scripts/site/interactives/flows.ts). |
Use when
- The flow sections (transform, creation) and the Govern and Roles pages (layers). Why: A process reads faster as steps than as prose.
Do not use when
- For a single step. Why: A sentence is enough.
Anatomy
| Part | What it is |
|---|---|
| root | figure.visual.ix-fl |
| title | p.ix-fl-title |
| steps | ol.ix-fl-steps |
| tree | the layers tree with lock levels |
Made of: figure-frame, caption.
Used in: pages directly.
Variants
| Variant | When | Why |
|---|---|---|
| transform | Changing an existing system. | Steps from audit to governed system. |
| creation | Starting with no system. | Steps from Loom Base to your own. |
| layers | Many brands or products. | Shows how far a rule can bend below its layer. |
States
| State | Rendered or not applicable |
|---|---|
| default | default |
| hover | Not applicable: The flows and layers tree is not interactive, so it has no hover state. |
| focus-visible | Not applicable: The flows and layers tree does not take focus; links and buttons inside it carry their own focus ring. |
| active | Not applicable: The flows and layers tree cannot be pressed. |
| disabled | Not applicable: The flows and layers tree has nothing to disable. |
| loading | Not applicable: The flows and layers tree is rendered at build time and is complete when the page loads. |
| empty | Not applicable: The flows and layers tree is not rendered without content; the builder skips it. |
| error | Not applicable: The flows and layers tree shows no data that can fail. |
| current | Not applicable: The flows and layers tree has no current item. |
| visited | Not applicable: The flows and layers tree is not a link. |
| expanded | Not applicable: The flows and layers tree does not open or close. |

Layout
| Aspect | Value |
|---|---|
| breakpoints | Required review at 390, 768, 1024 and 1440 px; execution is not implied by this declaration; the figure reflows to one column under 768 px. |
| wrapping | Labels wrap; drawings scale to the column. |
| textExpansion | Japanese labels are 20 to 40% longer and wrap inside their cells. |
Spacing and rhythm
| Aspect | Value |
|---|---|
| internal | Inside the Figure frame's --space-7 padding. |
| external | --space-9 above and below in prose. |
| rhythm | After the text whose claim it proves. |
Motion
| Aspect | Value |
|---|---|
| None | A record is evidence: it holds still so it can be read. |
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 | figure, named by its caption |
| name | The caption, and a text alternative for any drawing |
| keyboard | Not interactive unless stated. |
| focus | Links inside are in reading order. |
| screenReader | Reads the figure's text and caption; drawings have role=img with a description. |
| contrast | Ink on surface 14:1; dyes used only as marks with their words. |
| target | Not a target. |
Content
| Slot | Length | Voice |
|---|---|---|
| step | 8 words | Verb first |
Good: “Audit what you have”
Bad: “Synergise”
Japanese: i18n.ts ix.fl.*.
Icons and illustrations
None: this element uses no icon or illustration of its own.
Decisions and exceptions
Usage
21 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.
