-/**
- * Client-side live preview for the floor-plan editor.
- *
- * Every tile / door / thickness / wallHeight change in the editor
- * is applied IMMEDIATELY to the 3D room behind the editor card
- * via the renderer's local `RoomMessageHandler.applyFloorModelLocally`
- * (added in the renderer's `feat/floorplan-live-preview` branch).
- * Nothing is sent to the server until the user explicitly clicks
- * Save — at that point `FloorplanEditorView` fires the
- * `UpdateFloorPropertiesMessageComposer` directly.
- *
- * Closing the editor without saving leaves the live preview
- * in place visually. To restore the pre-edit room, call `revert`
- * — it re-applies the baseline payload locally. The next
- * `FloorHeightMapEvent` from the server (e.g. on room re-enter)
- * also wins and overwrites whatever preview is in place.
- *
- * Thickness changes additionally call
- * `RoomEngine.updateRoomInstancePlaneThickness` for zero-latency
- * wall/floor depth feedback (the full geometry rebuild that
- * `applyFloorModelLocally` performs already reflects the new
- * thickness in its plane data, but the dedicated thickness
- * setter is cheaper and updates instantly as a slider is dragged).
