Fixed critical validation errors caused by WGSL vec3<f32> alignment mismatches.
Root cause:
- WGSL vec3<f32> has 16-byte alignment (not 12 bytes)
- Using vec3 for padding created unpredictable struct layouts
- C++ struct size != WGSL struct size → validation errors
Solution:
- Changed circle_mask_compute.wgsl EffectParams padding
- Replaced _pad: vec3<f32> with three separate f32 fields
- Now both C++ and WGSL calculate 16 bytes consistently
Results:
- demo64k: 0 WebGPU validation errors
- Test suite: 32/33 passing (97%)
- All shader compilation tests passing
Files modified:
- assets/final/shaders/circle_mask_compute.wgsl
- TODO.md (updated task status)
- PROJECT_CONTEXT.md (updated test results)
- HANDOFF_2026-02-09_UniformAlignment.md (technical writeup)
Note: DemoEffectsTest failure is unrelated (wgpu_native library bug)

- Implemented VignetteEffect, including its shader, parameters, and sequence integration.
- Added VignetteEffect to demo_effects.h, shaders.cc/h, and asset definitions.
- Updated seq_compiler to handle VignetteEffect parameters.
- Added VignetteEffect to test suite and updated expected counts.
- Ensured all changes build and tests pass.
