Proves the unified (nodeId, slotId) slot contract on a procedural generator, beyond items and walls. A shelf now exposes three paintable slots — shelves / frame / back — painted through the same PaintCapability dispatch and the same node.slots: Record<slotId, MaterialRef> shape items use. Foundation (shared, reusable by future procedural kinds): - core: SlotDeclaration type + capabilities.slots(node) registry declaration; GeometryContext gains `materials` so a pure builder can resolve scene:<id> slot refs without importing useScene. - viewer GeometrySystem: threads the scene material library into every builder ctx, and re-dirties (bypassing the geometryKey skip) any geometry node that references a scene material when that material changes — so editing a custom colour propagates to every shelf using it, matching items. Shelf: - schema: slots: Record<string, MaterialRef> (mirrors ItemNode). - geometry: per-slot material resolution (slot override -> legacy whole-shelf -> declared default colour); every mesh stamped with userData.slotId; DEFAULT_SHELF_MATERIAL retired (declared default gives identical off-white). - paint.ts: PaintCapability (resolveRole from userData.slotId, scene-material commit for one-off colours, preview restricted to __fromGeometry meshes so hosted items aren't ghosted, getEffectiveMaterial incl. legacy fallback). - definition: paint + slots capabilities; slots folded into geometryKey.
