- Any failure of a source image or SteamGridDB (HTTPException, odd JSON) now
becomes a warning and generated art, never an aborted install; refresh-art
--all reports each app and carries on.
- URL artwork goes through apk_sources._images: public addresses only, at most
three redirects, and one overall deadline for all of an install's fetches.
- PNGs are checked from their header only (any depth or interlace; Steam's
Chromium decodes them), JPEGs may have trailing padding, and 4K screenshots
are within limits. The slow pure-Python decoder is gone.
- SteamGridDB title matching keeps letters of every script and never matches
on an empty name. One warning per source slot, not per candidate.
