/* Thumbnail-wall gallery, built like a phone photo library: tight gutters,
       no labels on the cells, every fact living in the card that opens on tap.

       Unlike a phone's square-crop grid, each thumbnail keeps its native
       aspect ratio — 16:9 visualizers stay wide, 9:16 reels stay tall, the
       square stings stay square. Nothing is cropped. The layout is a masonry
       wall: a small packer places each tile in the shortest gap that fits it,
       choosing tiles out of sequence when that keeps the columns level. */
