/* ──────────────────────────────────────────────────────────
   THE LIVING ROOM (/living-room). See design.md §12.
   A photographed room you shop by looking around it. Hover an
   object we sell and the room dims, the object lifts out with a
   white glow and a price tag. Click for a quick view (wall prints
   go to /prints; the leaning rack opens a flip-through). Touch: pulsing dots, tap = tag, tap
   again = open. Everything outside the photo stays monochrome
   (design.md §2): the room is the art, the UI keeps out of it.
