Rewrite workshop 01: Media library #328

Part of #326.

Questions

• A photo as a standalone asset, without a shot or a rig
• Sources: phone, upload
• Original resolution (today only a 1280 px copy is kept)
• Optional facets that can be added later: position, capture device, optics
• What a media item owns

As-is sources

photos table, apps/worker/src/shots.ts, docs/features/new-shot.md

Format

No product code. I prepare docs/rewrite/01-media.md with the as-is state (with file paths), the problems and leaks, a proposal and the open questions; mockups go to docs/rewrite/mockups/. The owner decides, the decisions are recorded in the page's "Decided" section and here, and the PR is merged into rewrite/plan.
