  /* The room-theme defaults (--wall, --floor, --wood, --glow, --accent,
     --haze, --lamp-size) and the CSS-3D world box (--world-w/h, --fit)
     lived here until phase 10. Every one of them existed for scene.css
     and themes.css, which are gone: a room's palette now goes straight
     from rooms.js's `pal` into three.js materials and canvas textures,
     with no CSS custom property in between. Phase 8's rule — a rule that
     matches nothing is the thing that actually rots, because the next
     person to read it believes it still does something. (--oxblood and
     --night-2 went with them; both had already been unused for longer
     than this phase.) */
