 - [ ] **Task #37: Asset Ingestion:** Update `asset_packer` to handle the new 3D binary format.
     - [ ] **Task #38: Runtime Loader:** Implement a minimal C++ parser to load the scene data into the ECS/Renderer.
 
-- [ ] **Task #18-B: GPU BVH & Shadows** (Optimization)
-    - [ ] **Upload BVH:** Create a storage buffer for `BVHNode` data and upload the CPU-built BVH every frame in `Renderer3D`.
-    - [ ] **Shader Traversal:** Implement stack-based BVH traversal in `scene_query.wgsl` to replace the linear loop in `map_scene`.
-    - [ ] **Shadow Optimization:** Use the BVH traversal for `calc_shadow` to skip occluded objects efficiently.

+- [ ] **Task #58: Advanced Shader Factorization**: Further factorize WGSL code into smaller, reusable snippets.
+- [ ] **Task #59: Comprehensive RNG Library**: Add WGSL snippets for float/vec2/vec3 noise (Perlin, Gyroid, etc.) and random number generators.
