Interactive floor plan library for expos and events

/**
 * Where the chunk-injected `<style>` elements live between plans.
 *
 * A chunk injects its CSS once per page, when it first evaluates
 * (`vite/per-chunk-css-injection.ts`), so the elements have to outlive every
 * plan: it registers each one on `window.__efpStyleElements`, and
 * `floorplan.loader` adopts the whole registry into each new container —
 * `appendChild` *moving* every element out of the previous, discarded one.
 * That migration is why a swap leaves the node count flat instead of stacking
 * a stylesheet set per generation, and it is why `resetGlobalVariables()`
 * deliberately skips this one key.
 *
 * It has one edge, though, and only on the destroy that no `load()` follows:
 * the registry still points at elements whose parent is the dead plan's
 * ShadowRoot. A node keeps its parent reachable, so a single adopted `<style>`
 * pins that root, its host and the ~7,200-node tree under it for the life of
 * the page.
 *
 * Parking cuts that edge without giving up re-adoption.
 */
/**
 * Moves every registered `<style>` out of the container being torn down and
 * into {@link parkingLot}, leaving `window.__efpStyleElements` itself intact —
 * the next `load()` adopts them out of the holder exactly as it would out of a
 * previous plan's container.
