- The background worker now also gives models without a thumbnail one:
an embedded 3MF/plate preview, else a picture uploaded with the model,
else a 3MF preview or picture inside one of its archives, else a render
of an STL/OBJ/3MF (loose or inside an archive).
- tools/render_thumbnail.py renders without a GPU: meshes are simplified
per distinct part (the 8M-face lion project renders in ~8 s / ~200 MB),
3MF projects show their first plate in filament colours, and only
camera-facing faces are painted (inside-out meshes and mirrored parts are
re-oriented first).
- models.thumbnail_status stops retries when there's nothing to use; adding
files clears it. The browser now only renders FBX/STEP/3DM thumbnails.
- The library checks back while fingerprints or thumbnails are pending and
refreshes when they land.
- Python sidecar needs pillow and fast-simplification; compose keeps the
archive extraction cache in a volume. README covers the phase 2 features.
