User-reported regressions on the 1:1 legacy ports: slab/ceiling moves were slow (polygon CSG rebuilds per scene.update tick), fence moves teleported briefly on commit (residual mesh.position offset survived the geometry rebuild). All three now use the same live-drag pattern the legacy fence move was designed for: - During drag, write only to `sceneRegistry.nodes.get(id).position` + `useLiveTransforms`. No `scene.update`, no polygon rebuild, no React re-render of geometry. - History stays UNPAUSED — scene state isn't changing. - On commit, a single `scene.update` writes the translated polygon (or fence start/end + linked-fence cascade). Recorded as one natural undo step. - Tools leave `mesh.position` at the drag delta on commit; GeometrySystem / CeilingSystem reset it to (0,0,0) when they rebuild the geometry on the next frame. By the time position clears, the new geometry is in place — no teleport. Two framework changes enable this: - `GeometrySystem` (viewer/systems/geometry) now resets `group.position` + `group.rotation` after every rebuild, matching the legacy `FenceSystem.updateFenceGeometry` behavior. Tools that translate the group during live-drag can rely on the reset. - Legacy `CeilingSystem.updateCeilingGeometry` extends its existing `position.y` reset to cover X/Z too — previously it left X/Z at the drag delta after rebuild, double-translating the visual.

// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'
// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)
