/* The room viewer (js/room-media.js), direction C "Monograph", rolled in from km-lab/c on 2026-11-08 (previous: *.pre-kmC-20261108). A room's story set like a page from a museum catalogue: a lit cover, then an essay of
   plates (photo plus its label) and rows of photos on a ground tinted by the room's own light. Blinker Light throughout, the site's tokens.
   Every photo sits at its own shape and is never drawn wider than its source can hold (--nw is the source's pixel width, --ar its shape).
   Each photo lights the wall behind it in its own sampled colour (--glow). Motion is arrival only: things settle once, transform and opacity. */
