Kernels in fx_generate.wgsl mirror the CPU effects; wipe edges use f64
per-column/per-row terms uploaded as (hi, lo) pairs. CPU helpers shared
with the GPU are now public (camera_lens_spans, gen_mode, pattern_kind,
GrainLook, place_layer). GPU tests in tests_fx_generate.rs.

Compute kernels in shaders/fx_distort.wgsl mirroring the CPU effects; per-row/column
structure (map coordinates, wave phase, tile bounds, mesh triangle buckets) is computed
in f64 on the CPU and uploaded. Displacement Map fetches its map layer through the
effect host as the CPU does and samples it on the GPU. CPU oracle tests in
tests_fx_distort.rs.

- Persistence: settings, shortcuts, recent projects, imported media, saved projects and
auto-saves live in OPFS (IndexedDB fallback) through an in-memory mirror flushed in the
background (apps/effectcraft-web/src/store.rs, persist.rs); ConfigStore gains FileOps so
auto-save / recovery work in the browser store; the session snapshot restores the last
project + editor state on reload; File > Open Recent works from storage.
- Audio: Web Audio output (AudioWorklet, ScriptProcessor fallback) fed by AudioPlayback::pump
on wasm32; A/V sync from AudioContext.currentTime; meters; unlock on first gesture.
- Background jobs: engine::offload (WorkerRequest/WorkerReply protocol, Offload trait,
run_request); Render Queue, tracker, mask tracker, Warp Stabilizer and Roto Freeze run in Web
Workers (a second engine instance on the shared compiled module), progress streamed back;
cancel terminates the worker.
- GPU: WebGPU viewer frames drawn straight from the compositor's texture (gpu_display on
wasm32 when the viewer draws plainly); async readback (Gpu::read_display_async) for pixels.
- PWA: manifest, service worker precaching the build (xtask fills list/version), icons copied
from assets/app-icon; COOP/COEP kept from cached responses; offline reload works.
- window.effectcraft: saveToBrowser, listStored, removeStored, flush; info() reports storage,
audio, gpu, workers.
- Tests: native store + protocol + offload (render, track, cancel) tests; smoke.mjs extended
(GPU path, worker render responsiveness, audio gesture + playback, reload persistence,
Open Recent, offline reload).

Advanced 3D comps render their 3D runs as one scene of world-space triangles: model and
primitive layers (meshes, skinning, animation clips by layer time), extruded text/shape
layers, and textured cards for every other layer with their Material Options. Shading is
physically based in linear light: Cook-Torrance GGX + Lambert for parallel/spot/point lights
(AE falloff and cone), ambient lights, image-based light from an Environment light's layer
(equirectangular; cosine irradiance map + roughness mip chain + split-sum BRDF fit), and
PCF shadow maps (spot/parallel/point cube faces). 2x2 SSAA, depth of field as a gather blur
by circle of confusion, back to the working encoding.
The software rasteriser (depth buffer, top-left rule, perspective-correct, opaque visibility
then sorted transparent blending) is the reference and CI path; effectcraft-gpu implements
Accelerator::raster_3d with a wgpu render pipeline (advanced3d.wgsl) and matches it within
tolerance. Environment layers are hidden from both renderers.

New L3 crate effectcraft-gpu: a wgpu compute backend for the per-frame
compositing walk (layer transforms with the CPU's nearest/bilinear/bicubic
sampling and minification pre-filter, motion-blur accumulation, track
mattes, Preserve Transparency, layer style passes and knockout, all 38
blend modes as a WGSL port of color::blend, 8/16 bpc clamp+quantise,
colour-space conversions). 3D runs, adjustment and wireframe layers run on
the CPU between GPU steps. GPU effects with the CPU semantics: Gaussian,
Fast Box and Directional Blur, Glow, Levels, Curves, Hue/Saturation, Tint,
Fill, Gradient Ramp, Fractal Noise, Drop Shadow, Brightness & Contrast,
Exposure, Invert, Transform (registry gpu badge from effects::GPU_EFFECTS).
render: Backend (Cpu/Gpu/Auto) in RenderOpts, the Accelerator trait and
Renderer::accel, GPU effect chains in the effect stack, hooks for the GPU
walk. Project setting gpu_acceleration (Mercury GPU Acceleration / Software
Only), render.backend command, file.projectSettings renderer. Session and
Render Queue exports carry the accelerator. CLI --gpu and bench --gpu.
Tests compare GPU vs CPU renders (blend modes x bit depths, transforms,
masks, mattes, motion blur, colour management, styles, collapse,
adjustment fallback, every GPU effect) and skip without an adapter.
