…ent-math, remove item-mesh-metadata system - Replace runtime mesh-based bounding-box computation with static dimension-based polygons for item footprints - Add snapUpToGridStep() and getGridAlignedDimensions() to placement-math for grid-cell-aligned placement wireframes - Add expandBoundsToGrid() to use-placement-coordinator for consistent wireframe snapping - Add currentCursorRotationY to PlacementContext; preserve world orientation across item-surface transitions - Fix item detach from surface: use worldToBuildingLocal() instead of event.localPosition to avoid coordinate-space jump - Subscribe to useLiveTransforms in FloorplanPanel during placement so R/T keyboard rotation refreshes the 2D overlay immediately - Fix FloorplanItemImage rotation (+180° to account for top-down camera capture orientation) - Simplify spatial-grid-manager: single dimension-based getItemLocalBounds(), removes runtime mesh-metadata path - Remove item-mesh-metadata system (compute-item-mesh-metadata, item-mesh-metadata-system, sync-request)

What this does
Replaces runtime mesh-based bounding-box computation with static dimension-based polygons for item footprints in the 2D floorplan. Previously, a per-frame convex-hull + minimum-area-rect pass over loaded mesh vertices produced the footprint — expensive and inconsistent with the 3D side where dimensions are the source of truth.
Grid-aligned placement wireframe: adds
snapUpToGridStep()andgetGridAlignedDimensions()so the green/red placement box always snaps to a full grid cell, making small items visually reserve the space they actually occupy.expandBoundsToGrid()in the placement coordinator expands the wireframe consistently across floor/ceiling/wall placements.Preserves world rotation across surface transitions: adds
currentCursorRotationYtoPlacementContextso items don't jump orientation when dragged from floor onto a rotated surface item.Fixes item detach from surface: uses building-local world conversion instead of surface-local
event.localPositionto prevent the wireframe teleporting on detach.Floorplan overlay refresh: subscribes to
useLiveTransformsduring item placement so R/T keyboard rotation updates the 2D underlay immediately without requiring a mouse move.Fixes
FloorplanItemImagerotation by +180° to account for top-down camera capture orientation.Removes the
item-mesh-metadatasystem (compute-item-mesh-metadata,item-mesh-metadata-system,sync-request) — no longer needed since footprints use dimensions directly.
