/* The playable Ascenseur board on gkw.games/ascenseur.
   Mirrors the game's "Signal" puzzle screen: paper, ink, one vermilion, Archivo 800,
   zero radius, hard offset shadows. Geometry comes from JS as custom properties:
   --w (board width), --band (floor height), --board-h, --shaft-x, --shaft-w,
   --car-w, --car-h, --rule. Everything is namespaced under .demo / .dm-. */
