Pin exact CPU pixel hashes of the simulation effects refactored into shared
GPU plans in M13.23 (CC Rainfall/Snowfall/Star Burst/Bubbles/Drizzle/Hair/
Mr. Mercury, Caustics, Wave World, Foam, Shatter, Card Dance, Card Wipe):
404 frames over default and non-default settings, four times incl. a seek
backwards, 8 and 32 bpc, full and half resolution. Verified bit-identical
between 7a5a93b (before M13.23) and 808ca70 (after).

CC Rainfall, Snowfall, Star Burst, Bubbles, Drizzle, Hair, Mr. Mercury,
Caustics, Wave World, Foam, Shatter, Card Dance and Card Wipe render on the GPU
(fx_sim.rs / fx_sim.wgsl). The per-frame simulation / layout stays on the CPU
and is shared with the CPU effect through plans (effects::sprite_plan,
piece_plan, bubble_list, mercury_blobs, drizzle_drops, wave_world_plan,
caustics_setup); a tiled item rasteriser composites sprites, bubbles, blob
fields and textured pieces in the CPU's order and shading. Layer-dependent
sprite colours (refracting rain, star-burst and hair roots) are sampled per
pixel; piece plans read the frame back once.

- GPU in the browser: each frame worker opens its own WebGPU device (Gpu::request_deferred) and
renders the GPU compositor and GPU effects with deferred readbacks (effectcraft-gpu deferred):
readbacks keyed by content start with map_async and miss, the pass returns placeholders, the
layer cache's gate drops inserts, and FrameServer::resume renders again once the device
delivered. Backend Auto times whole frames per comp in the workers. Frames with effects go to
GPU workers instead of the page. CPU fallback without WebGPU in workers (?nogpuworkers).
- Fix: a WGSL constant (3.40282347e38) that Chrome rejects invalidated every GPU kernel in Chrome
(the page's compositor too); a test checks every float literal fits f32.
- Disk cache in the Origin Private File System: workers write sealed frame entries with sync
access handles (temp file + move), the page keeps the DiskIndex (LRU under the settings' limit,
at most half the quota) and reads hits instead of rendering; survives reloads; blue cache bar.
- Storage manager: Settings ▸ Disk ▸ Browser Storage (usage/quota, persistent storage, Clear
buttons, automation ids) and storage.info / storage.persist / storage.clear (StorageHost).
- Docs: web.md (GPU workers, deferred passes, disk cache, storage manager, threading design:
one engine instance per worker), architecture, preferences, parity (WEB-1), roadmap.
- Tests: deferred passes vs CPU on a real device, placeholder gating, frame server passes and
Auto, GPU worker routing + disk cache across a reload, storage commands and widgets, store
usage by kind; smoke test: GPU effect frames in workers with pixel parity, disk hits after a
reload, storage manager.

Timewarp without a Matte Layer is now planned once (time_fx::timewarp_plan: frames, shutter
instants, motion fields) and built by the CPU or the GPU from the plan; with a Matte Layer it
renders on the CPU (catalog::gpu_supported).

VR Blur, Chromatic Aberrations, Color Gradients, Converter (all projections and
cube layouts), De-Noise, Digital Glitch, Fractal Noise, Glow, Plane to Sphere,
Rotate Sphere, Sharpen and Sphere to Plane run on the GPU (fx_vr.rs /
fx_vr.wgsl) with the CPU's equirectangular maths: seam-wrapping, pole-continuing
sampling and latitude-widened box blurs, per eye for stereo layouts.

CC Environment now fades nearly transparent environment texels to black continuously
(colour / max(alpha, 1e-3)) instead of a hard 1e-6 un-premultiply cut-off, which turned the
filtered map's float noise into colour.

Apply Color LUT, OCIO CDL / Color Space / Display / File / Look Transform and
Color Profile Converter compile to colour programs (effects::color_program,
built next to the CPU effects) that fx_lut.wgsl interprets per pixel; LUTs
(1D, 3D, cineSpace shapers, inverses) are read from the storage buffer with the
CPU's nearest / trilinear / tetrahedral interpolation. Lumetri's Input LUT and
Look no longer force the CPU. Custom .ocio configs stay on the CPU.

3D Channel Extract, Cryptomatte, Depth Matte, Depth of Field, EXtractoR, Fog 3D,
ID Matte and IDentifier run on the GPU (fx_depth.rs / fx_depth.wgsl): aux planes
upload as a texture and are resampled onto the buffer grid with the CPU's index
arithmetic; tests compare against the CPU at 1x / 2x aux resolution, padded
buffers, half resolution and 8 / 32 bpc composites.

- footage.check: background footage check after File > Open (Progress panel), not an undo step
- timeline: track-matte / parent menus built only while open (was O(n^2) per frame);
expression-row lookup per layer; panels hold Arc<Comp> snapshots instead of deep clones
- Project panel: virtualised vertical scrolling, selection reveal, thumbnails rendered off
the UI thread
- effectcraft-cli bench --ops (engine::perf + ui-egui::bench)

- gpu: pooled working textures (released once every encoder that could read
them is submitted), shared zero images, reused readback staging buffers,
direct readback into Image; NaN-poisoned scratch images under test and
NaN-aware diffs; validation errors panic under test
- render: AutoPick (per comp / scale / path EWMA of CPU vs GPU frame times,
warm-up and periodic re-probe) behind Backend::Auto; viewer uses it too;
cached adjustment footprints (uploaded once)
- gpu fx_warp: Warp, Bezier Warp, CC Bend It, CC Page Turn, Smear, Reshape,
Color Emboss, Cartoon; sliding-histogram median for large radii; CC Power
Pin perspective < 100
- cli: bench --gpu reports Auto and per-frame upload / readback MB

Effect Controls: Lumetri RGB and hue/saturation curve graphs, Colorama's
palette wheel, Glow's colour map strip and Arbitrary Map curves, Reshape
correspondence buttons and viewer handles (all prop.set, one undo step per
gesture, automation ids). Preview panel scrolls; Composition/Timeline tabs
get close, label swatch and viewer lock; Effect Controls tab the layer
swatch; dropdowns elide long text. Fix the browser start (no default disk
cache folder on wasm32). Browser smoke test covers frame workers, waiting
renders and the Media Browser.
