FreeBSD's CI VM (Mesa llvmpipe over GL) failed 22 effectcraft-gpu tests:
- Advanced 3D's camera-depth target was R32Float, which GLES can't render to without
EXT_color_buffer_float: create_render_pipeline failed validation (release builds only log
that and draw nothing). The target is now R32Uint holding the f32 bits (renderable on every
backend, lossless), and GpuContext checks the adapter's format features (render attachment,
blendable colour) and independent blending up front; when they're missing the render
pipelines are never built and Advanced 3D renders on the CPU.
- Signed `%` in the shaders: naga emits GLSL `%`, undefined for negative operands, which broke
the VR effects' horizontal wrap and Cell Pattern's tiling. A shared `imod` never takes `%` of
a negative number.
- asin/acos: Mesa's are coarse approximations (~1e-4 rad), visible in every lens/sphere/cylinder
mapping. `asin_p`/`acos_p` (Cephes' asinf polynomial) are f32-accurate on every backend.
- "Could not lock adapter context": the GL backend has one context lock per adapter with a
timeout, so tests driving devices concurrently panic. Every gpu test helper that hands out a
device holds one process-wide lock for the calling test; ui_web_job_gpu's two device tests
share a lock too.
- On GL, up to 1 % of pixels may flip across a decision boundary (division through a
reciprocal, unfused fma); the GPU-vs-CPU comparisons allow that there only.
Also adds the FreeBSD workflow (from the FreeBSD CI PR) so this branch is checked there.

- GPU in browser job workers: each job worker opens its own WebGPU device
(deferred readbacks); the Render Queue export and the analyses' frame loops
are futures (render::passes, offload::run_request_async) whose frames
render in passes, awaiting the device between them. GPU particles and
Advanced 3D read back under keys too. workers.jobs reports passes and
readbacks; the smoke test measures them.
- Layer buffers in the browser's OPFS disk cache: frame workers back their
layer caches with a PrefetchStore; the page plans what to fetch before a
request from recent misses (LayerPrefetch over the shared DiskIndex).
- Templates embed footage (default on, size-capped with a warning) and
creating from a template extracts it next to the new project / into
browser storage.
- ICC LUT profiles (lut8/lut16/lutAtoB/lutBtoA, from the public ICC spec) in
Simulate Output > My Custom RGB, baked into a 3D LUT for the viewer.

The geometry stays on the CPU as per-frame plans shared with the CPU effects (bolts, mask
strokes, scribbles, contour segments, audio marks, glyph strokes, waves, flood-fill region,
eyedropper sample); segments and convex polygons are tile-binned and rasterised on the GPU
with the CPU's coverage functions. CPU output unchanged (gen_golden). CC Threads' exact ties
at round parameter values are a documented exception; Fractal stays on the CPU (needs f64).

render: three_d::adv::SplitRun (Renderer::split_adv_run) hands draw_run's split path to an
accelerator as data (main scene, special layers far to near, 3D mattes drawn solo);
Renderer::sky_draw / three_d::SkyDraw for Environment Light Background layers. gpu: the walk
draws skies (adv_sky kernel), resolves each special layer, hides it behind the nearer main
scene (occlude kernel) and composites it through the 2D path without readbacks.

Advanced 3D runs render entirely on the GPU: every motion-blur sub-sample
rasterised, resolved and averaged, the depth-based iris depth of field
(Classic 3D bokeh spans, highlight boost, progressive levels), the sRGB
encode and the composite over the GPU canvas (Accelerator::render_3d,
Renderer::prepare_adv_run, adv3d.wgsl). Wireframe outlines draw on the GPU.
Fixes NaN environment lookups for straight up/down normals on Metal.
bench --gpu gains an Advanced 3D comp (--adv3d).

sampleImage renders the sampled layer through the evaluating renderer's footage source
(EvalCtx::footage), cached per thread and frame. File > Import reads .json/.csv/.tsv as data
footage kept in the project. expr.errors collects failing expressions for the error bar;
expr.languageMenu lists the categorised Expression Language menu. Marker keys expose
protectedRegion and cue points; colorDepth, timeToFeetAndFrames, comp.activeCamera.

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.
