* v3 library: multi-candidate cover picker — select from list, media-server style
Auto-best already ships; this adds the "pick from a populated list" surface
Christian asked for, as ONE reusable component (song covers now; album/artist
art reuse the same picker later).
Server:
- GET /api/song/{filename}/art/candidates — assembles WITHOUT hoarding: the
Current image + its provenance, Pack art when present, and Cover Art Archive
candidates for the matched release (and any release ids stored on a review
row's candidates). New _caa_release_index() fetches the CAA release INDEX
json (image list + types + thumb sizes) through the existing throttle +
offline gate, cached as caa_index_{id}.json beside the covers (indexes are
stable). Capped at 12; fetched on demand. Demo-blocked (it spends the rate
budget) and offline → instant tiles only, no error.
Frontend: new static/v3/image-picker.js — window.__fbOpenImagePicker({filename,
title}), a body-appended singleton modal (match-review anatomy: overlay, focus
trap, Esc). Current image + provenance badge on the left; a tile grid on the
right whose instant tiles — Current, Pack original, Upload, Paste URL — work
immediately even offline, while CAA candidates load behind ONE /art/candidates
fetch with skeleton tiles + a "the source is rate-limited" caption. The fetch
is tied to an AbortController and cancelled when the modal closes.
Applying a pick reuses EXISTING routes so there's no new write path and the
design's key trick holds: a chosen cover POSTs to …/art/url (the override
lane — never evicted by the art-cache LRU, survives a re-match); "Pack
original" DELETEs the override; Upload POSTs …/art/upload (GIF stays
upload-only + local-only). Silent-on-success; the drawer/card art refreshes
via the existing cache-buster.
Entry points: the Details drawer art click (the old direct file dialog is now
the Upload tile) and a card ⋮ "Change cover…" action.
Tests: tests/test_art_candidates.py (matched row lists index images; review
row pulls in candidate releases; unmatched/offline → instant tiles only;
index cached, no second fetch; demo blocked) over a fake index seam.
30 pass with test_art_layer green (same seams). node --check clean; tailwind
rebuilt for the new file.

* fix(v3 cover picker): uiPrompt over window.prompt, visible-only focus trap, gate CAA to matched rows, index-cache lock, abort-on-reopen; +traversal tests
