The drag-with-grab-cursor model was wrong design — 3D doesn't drag,
it uses select → inspector "Move" button → click-to-place. Floor
plan should match. Drag also had a coord-conversion bug (used outer
<svg> CTM instead of the floorplanSceneRef <g>, so screen→meter
conversion didn't account for the floor plan's pan/zoom/building-
rotation transforms).
Strips the drag pointerdown/move/up handlers, the imperative
transform override, the temporal pause bracketing, and the global
window listeners. Cursor goes back to 'pointer'. Only click-to-
select remains.
The right pattern (move via inspector / action menu + cursor-driven
placement) needs:
- Registry-aware FloorplanActionMenuLayer path
- Generic movingNode handler in floor-plan-panel for any registered
kind with capabilities.movable
- Shared floorplanSceneRef for accurate coord conversion
Both flagged in the plan as Phase 4 follow-on gaps with their
acceptance criteria. 3D-realtime-sync-while-moving is documented as
deferred (legacy doesn't do it for any kind either; design + ship
in a dedicated PR later).
