fix: Complete auxiliary texture initialization fix

2026-02-11T10:58:24Z

Root cause: After swapping init/resize order, effects with Renderer3D crashed because resize() called before init() tried to use uninitialized GPU resources. Changes: - Add guards in FlashCubeEffect::resize() and Hybrid3DEffect::resize() to check ctx_.device before calling renderer_.resize() - Remove lazy initialization remnants from CircleMaskEffect and CNNEffect - Register auxiliary textures directly in init() (width_/height_ already set) - Remove ensure_texture() methods and texture_initialized_ flags All 36 tests passing. Demo runs without crashes. Co-Authored-By: Claude Sonnet 4.5

feat: Add coordinate-aware CNN layer 0 for position-dependent stylization

2026-02-10T09:27:44Z

- Implement CoordConv2d custom layer accepting (x,y) patch center - Split layer 0 weights: rgba_weights (9x mat4x4) + coord_weights (mat2x4) - Add *_with_coord() functions to 3x3/5x5/7x7 convolution shaders - Update training script to generate coordinate grid and export split weights - Regenerate placeholder weights with new format Size impact: +32B coord weights + ~100B shader code = +132B total All 36 tests passing (100%) handoff(Claude): CNN coordinate awareness implemented, ready for training Co-Authored-By: Claude Sonnet 4.5
