User-visible follow-ups after first running the Phase 2 spike.
Spawn tool now matches legacy UX:
- CursorSphere from @pascal-app/editor for the placement indicator
(ring + line + tool-icon tooltip) — was a plain sphere mesh.
- Emits sfx:structure-build on commit + setTool(null) + setMode
('select') to exit build mode, matching legacy spawn-tool.
Shelf tool placement:
- Emits sfx:structure-build on commit.
- Cursor preview now shows top board + brackets (was just the top),
matching what gets placed.
Shelf selectable from the 3D canvas:
- ShelfEvent type added to @pascal-app/core/events/bus.
- 'shelf' added to NodeConfig in useNodeEvents.
- ShelfRenderer wires `useNodeEvents(node, 'shelf')` handlers onto
every mesh. Clicks/hovers now bubble through the editor's selection
manager and update useViewer.selection.
Shelf appears in the sidebar:
- ShelfTreeNode component (mirrors spawn-tree-node's shape +
selection/hover/rename wiring; lucide Layers icon).
- TreeNode dispatcher adds a `case 'shelf':` arm.
Framework changes:
- @pascal-app/editor exports CursorSphere alongside triggerSFX.
- @pascal-app/nodes now declares @pascal-app/editor as peer/dev dep.
Pre-existing typecheck errors in @pascal-app/editor (ceiling-tree-node,
fence-tree-node, slab-tree-node, scene.ts) are unchanged — present on
main and not introduced by this commit.
630 tests still pass.
