+# Manual accessibility review checklist
+
+Automated axe checks do not establish WCAG conformance. A human reviewer must
+review all three route records in `artifacts/tests/a11y-manual/` against one
+release candidate and sign them. Copy the template fields exactly; the gate
+rejects blank identity/timestamp/signature fields, pending verdicts, mismatched
+release IDs, or missing routes.
+
+Allowed item verdicts:
+
+- `pass`
+- `not-applicable (<specific reason>)`
+
+Required record:
+
+```text
+Status: reviewed
+Route ID: APP_HOME
+Release ID: <immutable release ID>
+Reviewer: <human reviewer identity>
+Reviewed at: <RFC 3339 timestamp>
+Signature: <reviewer identity or approved signature reference>
+Attestation: accepted
+M1 Keyboard: pass
+M2 Visible focus: pass
+M3 Route focus: pass
+M4 Modal focus: not-applicable (no modal on this route)
+M5 Error association: not-applicable (no form error on this route)
+M6 Color signal: pass
+M7 Reduced motion: pass
+Screen reader: pass
+Notes: <observations and linked defect IDs>
+```
+
+The reviewer must verify:
+
+- M1: every action works without a pointing device
+- M2: every focused element has a visible indicator
+- M3: route transitions move focus to a deterministic target
+- M4: modal focus is trapped and restored, when a modal exists
+- M5: errors are programmatically associated with their controls, when present
+- M6: state never relies on color alone
+- M7: non-essential motion is suppressed with reduced-motion preference
+- Screen reader: headings, live regions, errors, and actions are announced once
+
+Passing automated evidence means only that tested pages had no critical or
+serious axe findings under the recorded browser run.

+# Design-token styling contract
+
+`src/presentation/styles/theme.css` is the styling SSOT. Components consume
+semantic color, spacing, typography, and radius tokens through static Tailwind
+classes.
+
+Arbitrary-value policy:
+
+- prefer a named semantic token
+- bracket values are allowed only for one-off platform constraints that cannot
+  be expressed by the current scale
+- a repeated bracket value must be promoted into `@theme`
+- user-controlled or runtime-composed class strings are forbidden
+- class variants must be selected from a closed static map
+
+The removable sample may demonstrate tokens, but product modules must not
+import from `src/sample/contract-fixture`.
