- Guard _buildCache in merged-outline-node against stale/disposed
Object3D refs that cause TypeError on .id access during render
- Reset children array when duplicating roofs to prevent inconsistent
parent-child relationships (matching existing stair behavior)
- Use obj?.parent check in EditorOutlinerSync to ensure objects are
still in the scene graph before adding to outliner arrays
- Resume temporal state on parse failure to prevent undo/redo freeze
Closes#232
* fix: allow deleting walls and slabs via floating action menu
Walls and slabs were excluded from ALLOWED_TYPES in FloatingActionMenu,
so no delete UI appeared when selecting them. Added wall/slab to the
allowed types and show only the delete button (no move/duplicate) since
they are structural elements.
Usage: switch to select mode (V), click a wall or slab, then use the
floating trash icon or press Delete/Backspace to remove it.
Closes#156
* fix: offset delete button higher on walls/slabs to avoid covering measurement labels
* feat: implement sledgehammer-style delete mode
Clicking the trash icon in the floating action menu now activates a
persistent delete mode (like The Sims sledgehammer tool) instead of
deleting immediately. Users can then click objects on the canvas to
delete them one by one. Press V or Escape to exit delete mode.
- Wire delete mode clicks/hover in SelectionManager
- Add D keyboard shortcut to activate delete mode
- Change floating menu delete button to activate delete mode
- Add crosshair cursor when delete mode is active
