 - The web workspace now has a Vue/Vite public catalog shell with Vue Router, a catalog API service, search composable, loading/error/empty states, and responsive search-first styling.
 - The web catalog now provides keyboard-accessible listing cards with stable `/listings/:id` links, a public listing detail page, and service-level detail loading/error handling.
 - Catalog search and pagination are synchronized to the browser URL (`q` and `page`) with accessible previous/next controls; the web port `5173` is declared in the project port registry.
+- The web catalog includes a stable `/products/:slug` product detail route with API-backed loading, not-found/error states, and semantic product facts.
 - `ImageStorage`, traversal-safe local storage, multipart upload transport, and binary signature validation are implemented; derivative processing remains.
 - Derivative orchestration now defines thumbnail, medium, and large WebP storage outputs behind an injected renderer; the concrete worker-backed renderer remains.
 - The worker owns an image derivative job runner with explicit processing, completion, and failure outcomes; queue transport and persistent job records remain.
