|
|
# • else 302 → the Discogs thumb. Discogs already serves a ~150px q40 WebP (tiny), and a BROWSER can
|
|
# load it even though server-side fetch is Cloudflare-403'd — so we redirect rather than proxy.

# DISC_IMAGE_DIR is CONFIGURABLE (default now; per-store storage override later when shops host their own).

|
# Local copies get populated by a backfill from WowPlatter's already-downloaded images / the harvester —
|
|
# NOT by a server-side i.discogs fetch (that's blocked). Until then, the redirect gives working tiny WebP.
