The gallery grid loaded every output at full size: a 1024x1536 PNG decodes to
about 6 MB in the browser, so a few pages of outputs held hundreds of MB to
GBs of browser memory and graphics memory. Cards now use a cached 512 px WebP
from /anomalous/output_thumbnail (the model cards' thumbnail cache; about
0.7 MB decoded); dragging to the canvas, the viewer and the workbench still use
the original. When the browser has been closed for 90 s its gallery images are
released like the model grid, and reopening on the gallery reloads them.
