Schema v2 adds style/rows/columns/withBack/withSides/withBottom/bracketStyle and a `children: ItemNode[]` field for item hosting. Schema-level defaults preserve the v1 wall-shelf visual so existing scenes load unchanged; the placement tool spreads `shelfDefinition.defaults()` for fresh shelves (cubby 3x2 at 1m × 0.5m × 1.8m, thickness 0.05m, back/sides/bottom on). Four style geometries (wall-shelf / bookshelf / open-rack / cubby) share the dimensional schema. `shelfRowSurfaceYs` exposes one host surface per row, plus the bottom-board top when `withBottom` is on for cubby / bookshelf. Material is a single paintable surface (same shape walls / slabs / stairs use); `DEFAULT_SHELF_MATERIAL` aligned with `DEFAULT_WALL_MATERIAL` so unpainted shelves read as the canonical off-white. Preview clones each cached material before mutating `transparent / opacity` on the ghost — without the clone the mutation leaked into the cached `getShelfMaterial` instance every committed shelf was using, rendering them all see-through after the first placement preview rendered. Store hardening: `migrateNodes` patches missing `children: []` on v1 shelves, and `updateNodesAction` reparenting tolerates a missing children array on the new parent. `MaterialTarget` enum adds `'shelf'` so paint mode picks up the kind.

const setLevelMode = useViewer(s => s.setLevelMode)
const wallMode = useViewer(s => s.wallMode)
const setWallMode = useViewer(s => s.setWallMode)
return (
<div>
<button onClick={() => setLevelMode('stacked')}>Stacked</button>
<button onClick={() => setLevelMode('exploded')}>Exploded</button>
<button onClick={() => setWallMode('cutaway')}>Cutaway</button>

</div>
)
}
Asset CDN Helpers
import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'
// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → '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)
