Cards fetched the full cuts: a 400x600 poster (~38 KB) for a ~144px picture and the 1280x720 backdrop (~162 KB) for a ~212px shelf picture. The image proxy now also cuts thumb_sm (240x360) and art_sm (480x270), cached apart; card pictures (grid, shelves, collection tiles, Up next) carry both in srcset with sizes=auto, so the browser picks by laid-out width and DPR. Localdev: 17 KB a poster, 56 KB a backdrop. The detail page keeps the full cuts.

Cards fetched the 400×600 poster for a ~144px picture and the 1280×720 backdrop for a ~212px shelf
|

picture. The `_sm` variants are cut by Plex at a card's size and cached apart from the full ones; an
|

unknown variant still gets the full poster. DB lane (the proxy opens its own short session).
