/* ─────────────────────────────────────────────────────────────────────────
   Floor plan — realistic restaurant tables on a responsive canvas.

   Layout model: a fixed logical "world" holds the tables at percentage
   positions, so spacing maths is deterministic in world pixels. The world is
   auto-scaled to fit the viewport by the viewport controller
   (js/reservations/floor-viewport.js) — there is no zoom or pan; the whole plan
   is always shown and stays responsive. Status is shown by a coloured border +
   small badge — the tabletop is never colour-filled.

   Shared by the admin editor and the public booking view; admin-only
   affordances live under .floorplan-canvas--admin.
