+## Public route navigation — 2026-09-10
+
+- Catalog cards use router links with ordinary URL/open-in-new-tab behavior.
+- Catalog and public detail pages set descriptive browser titles. Detail titles
+  update to the product name or error message after loading.
+- Entry focuses the named main landmark with a visible keyboard outline. It is
+  programmatically focusable (`tabindex=-1`) without adding an extra Tab stop.
+  Query updates and asynchronous results do not move focus again.
+- Filtered catalog links carry their origin in `from`; “Back to catalog” restores
+  that URL. Only `/` and catalog query URLs are accepted; external or non-catalog
+  destinations fall back to `/`. Browser Back retains its normal history behavior.
+- Three public Playwright tests exercise keyboard navigation, query preservation,
+  browser Back, direct product links, not-found titles, safe return URLs, and a
+  delayed response while focus remains on the return link. They intercept public
+  API responses and do not require credentials or mutate production data.
+
+These checks verify browser focus, titles, and navigation behavior. Screen-reader
+speech and native browser zoom remain manual follow-ups from the earlier review.

 - Long detail text and seller contacts reflow, read-only condition badges no longer add inactive buttons to keyboard navigation, and detail loading/errors expose announcement roles.
 - Added keyboard, 320px reflow, 200% text enlargement, and detail-state regression stories. Browser review and its native-zoom/screen-reader limitations are recorded in `docs/ACCESSIBILITY.md`.

+### Latest Vertical Slice: Public Navigation Accessibility
+
+- Catalog cards use router links; catalog and detail pages have descriptive titles and named, focused main landmarks on entry.
+- Async responses and query updates preserve user focus. Filtered catalog URLs survive the explicit return link and browser Back; return destinations are restricted to the catalog.
+- Added three public browser navigation tests and return-path validation coverage; updated page/card Storybook interactions.
+- Validation: 166 API tests, 11 web tests, 3 public Playwright tests, production web build, Storybook build, and 32 Storybook suites / 93 tests. No API or persistence changes.
+- Screen-reader speech and native browser zoom remain manual review items; this slice verifies browser focus and title behavior.
+
+Next bounded slice: clearing configured seller contact methods. The Settings form currently converts blank email/phone values to omitted fields, so the server's partial-update merge retains old contacts. Support explicit removal through validation, settings UI/API, and public detail output, with edit/clear regression coverage.
