/* ── Visual Warehouse Map (PR 7) ───────────────────────────────────────────
 * Live, color-coded bin grid. Sits alongside the existing /warehouse/map
 * page (whose styles live in wms.css under the .map-shell / .loc-detail
 * blocks); this file owns only the new visual-map layout, cell palette,
 * indicator dots, and live-badge pulse.
 *
 * No selectors here overlap with the legacy .map-* classes — those stay
 * untouched. The new page roots at .vwm-shell so the two pages cannot
 * accidentally share theming.
 *
 * Spec reference: Docs/VisualWarehouseMap-Spec.md §7.4.
 * ─────────────────────────────────────────────────────────────────────── */
