+### Latest Vertical Slice: Public Seller Description
+
+- Sellers can save, edit, and clear an optional public description in Settings.
+- Descriptions are trimmed plain text, limited to 2,000 characters server-side, and stored in existing seller settings JSON without a migration.
+- Public listing and product detail pages render the description as escaped text with line breaks; public DTOs expose only the allowlisted field.
+- Dark-theme coverage also exposed and fixed insufficient status badge text contrast for Available, Pending, and Sold.
+- Coverage includes validation/partial-update/clearing tests, public HTTP contracts, PostgreSQL repository reads, settings edit/clear interactions, both public page integrations, and absent/plain-text/dark-theme component stories.
+- Validation: 166 API tests, 23 isolated PostgreSQL/Redis integration tests, 10 web tests, production web build, Storybook build, and Storybook interaction/accessibility runner (32 suites / 84 tests).
+
+Next bounded slice: review the public catalog → listing/product detail → seller contact journey with keyboard navigation, mobile layout, and 200% zoom; fix discovered accessibility issues and add regression stories/tests. Record manual results in `docs/ACCESSIBILITY.md`. This advances the documented accessibility milestone without requiring external provider credentials.
