 - [2026-02-12] Public portfolio baseline added with `/{locale}/portfolio` and `/{locale}/portfolio/{slug}`, including published-artwork filters (gallery/album/category/tag), rendition image streaming via web `/api/media/file/:id`, and media-aware artwork detail rendering.
 - [2026-02-12] Portfolio grouping controls completed in admin `/portfolio`: galleries/albums/categories/tags now support visibility and sort-order management (create/update/delete), and public tag filters now respect visibility.
 - [2026-02-12] Artwork refinement baseline completed: admin `/portfolio` now captures/edits medium, dimensions, year, framing, availability, publish state, and optional price visibility (`priceAmountCents` + `priceCurrency`), with public artwork detail rendering visible prices only.
+- [2026-02-12] Artwork rendition management completed: admin `/portfolio` supports `thumbnail/card/full/retina/custom` slot assignment with dimensions and primary flag, plus per-artwork rendition listing and delete controls.
 - [2026-02-12] Public UX pass: commission request flow now reports explicit invalid budget range errors, and header navigation now falls back to localized defaults (`home`, `portfolio`, `news`, `commissions`) when no CMS menu exists; seed data now creates those default menu entries.
 - [2026-02-12] Added `e2e/public-rendering.pw.ts` web coverage for fallback navigation visibility, portfolio routes, and commission submission validation (invalid budget range + successful submission path).
 - [2026-02-12] Testing execution is temporarily paused for delivery velocity: root test scripts are stubbed and CI test steps are disabled; all testing backlog is consolidated under `MVP 3: Testing and Quality`.
