Two issues kept the Photos → Places map blank once the SPA could boot:
- CSP `worker-src 'self'` blocked MapLibre GL, which spawns its web worker
from a blob: URL, so the map never constructed. Allow `worker-src
'self' blob:` ('self' still covers same-origin workers like delta-upload).
- `checkBasemap()` trusted `res.ok`, but the SPA fallback serves index.html
(HTTP 200, text/html) for any missing path — so a missing basemap.pmtiles
read as "present", and pmtiles.js then choked on HTML ("Wrong magic
number for PMTiles archive"). Reject text/html responses so an absent
basemap falls back cleanly to the themed blank style.
