|---|
| Id | arrow-link |
|---|
| Layer | Atoms |
|---|
| Category | navigation |
|---|
| Owner | Site system lead |
|---|
| Status | stable |

| Version | 1.0.0 |
|---|
| Source | apps/showcase/site/system/atoms/arrow-link.ts (private repository; the contract and the render function are this one module) |
|---|
| Version | Date | Change |
|---|
| 1.0.0 | 2026-10-26 | The 'go further' link at the end of a section, on its own line with the arrow. |
|---|
Use when
- A section ends and a page goes deeper into its claim. Why: The reader who wants proof finds it exactly where the claim ends.
- Two related next steps sit side by side. Why: Arrow links stay quieter than buttons, so the page's one action keeps its weight.
Do not use when
- The step is the page's main action. Why: That is the primary button's job.
- Inside a sentence. Why: In a sentence, a text link keeps the line readable.
Anatomy
| Part | What it is |
|---|
| root | p.more holding one or more a.arrow-link. |
|---|
| label | The words. |
|---|
| icon | The arrow (Icon atom), which moves 3 px on hover. |
|---|
Made of: icon, tokens:type, tokens:colour.
Used in: header, read-your-stylesheet, stage-finder, flow-section, founder-section, job-section, lead-section, problem-section, proof-section, tile-grid.
Variants
| Variant | When | Why |
|---|
| single | One next step. | Most sections have one place to go deeper. |
|---|
| pair | A demo and a page about the same claim. | Both proofs are offered side by side, without a second button. |
|---|
States
| State | Rendered or not applicable |
|---|
| default | Strong text, underlined |
|---|
| hover | The arrow moves 3 px right. |
|---|
| focus-visible | The --focus ring around the link. |
|---|
| active | Not applicable: Navigation is instant; no pressed state. |
|---|
| disabled | Not applicable: Never rendered without a destination. |
|---|
| loading | Not applicable: Static link. |
|---|
| empty | Not applicable: The builder drops a link list with no items. |
|---|
| error | Not applicable: Broken links fail the link test in tests/site/pages.spec.ts. |
|---|
| current | Not applicable: Points away from the current page by definition. |
|---|
| visited | Same colour: the arrow link is a next step, not a reading list. |
|---|
| expanded | Not applicable: Does not open anything. |
|---|
Tokens
| Part | Token |
|---|
| root.font | --type-strong |
|---|
| root.color | inherit (field text on dye fields) |
|---|
| icon.transition | --dur-slow --ease-standard |
|---|
| --arrow-link-gap-space-4 | var(--space-4) |
|---|
| --arrow-link-font-weight-weight-strong | var(--weight-strong) |
|---|
| --arrow-link-text-underline-offset-space-2 | var(--space-2) |
|---|
| --arrow-link-margin-top-space-8 | var(--space-8) |
|---|
Layout
| Aspect | Value |
|---|
| breakpoints | Required review at 390, 768, 1024 and 1440 px; execution is not implied by this declaration; a pair wraps onto two lines under 600 px. |
|---|
| wrapping | Wraps between links, never inside the arrow. |
|---|
| textExpansion | Japanese labels wrap inside the link. |
|---|
Spacing and rhythm
| Aspect | Value |
|---|
| internal | Gap --space-4 between label and arrow; --space-8 between links in a pair. |
|---|
| external | --space-7 above, the last element of its section. |
|---|
| rhythm | Always last in the section's reading order (D-SITE-005). |
|---|
Motion
| Aspect | Value |
|---|
| moves | The arrow, 3 px to the right. |
|---|
| trigger | Hover on pointer devices. |
|---|
| duration | --dur-slow |
|---|
| easing | --ease-standard |
|---|
| interruptible | Yes, it reverses from where it is. |
|---|
| reduced | Kept: a 3 px shift under 250 ms is not a vestibular trigger. |
|---|
| why | It shows the link leads onward, the same gesture as the button's shuttle. |
|---|
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 | link |
|---|
| name | The visible words |
|---|
| keyboard | Enter follows the link. |
|---|
| focus | In reading order. |
|---|
| screenReader | Reads the words; the arrow is hidden. |
|---|
| contrast | Inherits the section's text colour: 4.5:1 or better on cotton and every field. |
|---|
| target | 44 px tall line box, above the 24 px minimum. |
|---|
Content
| Slot | Length | Voice |
|---|
| label | 7 words | Name the destination or the proof: 'See the agent replay' |
|---|
Good: “What drift costs, and how to estimate yours” · “See the agent replay”
Bad: “Read more” · “More”
Japanese: Text comes from the page content; Japanese strings are reviewed per page (apps/showcase/site/loom/locales). Awaiting native review, as the banner on every Japanese page says.

Decisions and exceptions
Usage
365 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.
