27 hours	refactor(shaders): extract oct-normal encode/decode into math/normal snippet	skal
	New src/shaders/math/normal.wgsl: oct_encode, oct_decode, oct_encode_unorm, oct_decode_unorm. Registered in InitShaderComposer as "math/normal". Removed inline copies from gbuf_raster.wgsl and gbuf_pack.wgsl. 18/18 tests passing.
4 days	feat(cnn_v3): G-buffer phase 1 + training infrastructure	skal
	G-buffer (Phase 1): - Add NodeTypes GBUF_ALBEDO/DEPTH32/R8/RGBA32UINT to NodeRegistry - GBufferEffect: MRT raster pass (albedo+normal_mat+depth) + pack compute - Shaders: gbuf_raster.wgsl (MRT), gbuf_pack.wgsl (feature packing, 32B/px) - Shadow/SDF passes stubbed (placeholder textures), CMake integration deferred Training infrastructure (Phase 2): - blender_export.py: headless EXR export with all G-buffer render passes - pack_blender_sample.py: EXR → per-channel PNGs (oct-normals, 1/z depth) - pack_photo_sample.py: photo → zero-filled G-buffer sample layout handoff(Gemini): G-buffer phases 3-5 remain (U-Net shaders, CNNv3Effect, parity)
