/**
 * floor-plan.css — the room container, the SVG floor plan drawn from

 * their geometry, shape, and the plain (non-decorative) interaction states.
 *
 * No hover-scale, no gloss, no shadow, no pulse here by design — a device
 * changes only its border/outline on hover or focus, never its size or
