Canonical AI actions
Architecture: Preview runs on WebGPU / WGSL in the browser. Export runs on Vulkan / SPIR-V server-side. Both share the same .wgsl shader source — compiled to SPIR-V for Vulkan, consumed natively by WebGPU — so preview and export output are pixel-identical. Hardware video decode via NVDEC, encode via NVENC, zero-copy CUDA → Vulkan texture pool for ML inference results.
🎬
Post-Processing Pipeline
Dedicated shader pass per effect — same pipeline for preview (WebGPU) and export (Vulkan)
