/* ---- Artwork grid (bento/mosaic layout — tile shape driven by rarity) --
   Matches the original mockup's mosaic: mostly square tiles, with some
   wide and tall rectangles mixed in for visual rhythm. The source images
   are square (1:1); a non-square cell crops the image via object-fit:
   cover (same as every other tile) rather than stretching it — cropping a
   square photo into a rectangle is how every photo-grid mosaic works, it
   just shows less of the image, never a distorted one.
   Each card's exact grid-column/grid-row span is set inline by gallery.js
   (footprintFor()), picked deterministically per artwork so the mosaic is
   stable across reloads rather than reshuffling. grid-auto-rows is synced
   to the ACTUAL rendered column width in JS (gallery.js: syncTileUnit) so
   one grid unit is a true square at every screen size, which is what
   keeps square-footprint tiles square and gives rectangle tiles a clean
   2:1 ratio rather than an arbitrary one.
   grid-auto-flow: dense lets smaller tiles fill gaps left by bigger ones
   instead of leaving holes, so the layout stays packed as items of mixed
   size are added — the same technique behind the mockup's tight mosaic. */
