The PCF tap jitter was keyed on the receiver's 1/8-texel cell in the
shadow map. The GPU computes the receiver's map position with last-bit
differences from the CPU, so a receiver next to a cell line could take
another cell's jitter on one backend, and every tap moved. In a wide
penumbra that changed the coverage by several 8-bit levels:
gpu_matches_cpu_wide_penumbrae failed on Windows with 15 of 4159
shadowed pixels on an NVIDIA RTX 5080 and 22 on an AMD Radeon iGPU,
against a budget of 8.
tap_jitter now blends the hashes at the four corners of the cell by
the receiver's position in it, in shade.rs and in advanced3d.wgsl. At
the lattice points the jitter is the per-cell hash it was before. A
CPU test checks that the coverage does not jump at a lattice line.
Poison recovery, OsStr::to_str and char predicates only; S4325 casts are
f64 to f32 and stay.

Shadow maps use the full scene-derived size (point-light faces capped
at 2048) under a 26M-texel scene budget halved largest-first; the PCF
filter measures its reach in output pixels with a two-texel minimum,
samples texel centres on a jittered adaptive 5..10 grid, and compares
each texel against the receiver plane's own depth so wide kernels never
self-shadow lit casters. The WGSL mirror is parenthesised (Tint rejects
the old form) and guarded by a shader-wide grammar test; the CPU
reference and shader remain step-for-step parity-tested.
The Advanced 3D renderer folded Accepts Shadows (Off/On/Only) into a
bool, so a shadow catcher set to Only drew as an ordinary lit surface.
The material now carries shadows_only. Such a fragment draws black at
the strongest shadow a light casts on it, as Classic 3D does, and it
goes in the blended pass so what is behind it shows through. The CPU
shader and advanced3d.wgsl get the same branch.

Turning Solo on or off hides or shows every other layer at every frame, so it
now recaches the whole comp. The kept span is widened by the comp's shutter
(phase and angle), since a frame's motion blur samples cameras, lights and
transforms up to three frames away. Comp::any_solo is shared with the
renderer so both read Solo the same way.

Guide layers render only in their own comp's viewer: a nested renderer (precomp, collapsed
precomp in 2D, Classic 3D and Advanced 3D, comps read by effects, aux passes, the GPU walk's
resident precomps) now runs with guides off (Renderer::nested_opts), so a precomp's guide
layers no longer show in the parent comp's viewer or in a "Current Settings" render.
The Timeline layer and Composition viewer right-click menus (shared layer_menu) gain a
Guide Layer item (a plain toggle, no check mark) acting on the selection, and guide layers show a guide mark
before their name in the Timeline.

In After Effects solo is not time-dependent: while any AV layer is soloed,
non-soloed layers are excluded at every time. The renderer, nested/collapsed
3D paths, engine viewer helpers and viewer hit tests only counted solo layers
active at the current time, so outside the soloed layer's in-out range the
whole comp reappeared. Drop the time condition (audio already ignored it).
Update the #66 viewer regression test to the AE behaviour and add a render
test for it.

Problem: the extra panes of View > Switch View Layout were fixed to Top, Front and Right, and the 3D View menu only changed the main view.
Fix: every extra pane has a view selector (Active Camera, Default, Front, Left, Top, Back, Right, Bottom, Custom View 1-3). The choice is kept per comp in Views3D::panes (serde default, so older editor states load with Top/Front/Right) and set by the new command view.setPaneView {pane 0-3, view}. The Active Camera pane renders through the comp camera.

Problem: In Advanced 3D, an extruded shape or text layer was one mesh in
its paint colour. After Effects colours the front, bevel, side and back
of an extrusion separately (shape Contents ▸ Add ▸ Front/Bevel/Side/Back,
text Animate ▸ Front/Bevel/Side/Back), and EffectCraft had none of it.
Fix: The extruder can split its mesh by surface (front cap, bevel rings,
walls, back cap). Shape layers get Front / Bevel / Side / Back contents
items (layer.addShapeItem kinds frontColor…backColor, one item per
group, colouring every paint of the group and its nested groups; the
innermost wins). Text animators get Front / Bevel / Side / Back Color,
blended over the character's fill or stroke by the selection. Paints
with a surface colour render as one mesh per surface. Menus, the
Contents Add: pop-up and the menu translations list them. The other
surface material properties (Ambient, Diffuse, Specular, Metal,
Reflection, ...) remain.

`Renderer::mb_on` (render options × the comp's switch × the layer's switch as the precomp
layers above limit it) now decides everywhere:
- Mask motion blur checked only the comp's switch and the layer's own switch, so Render
Settings ▸ Motion Blur ▸ Off for All Layers and a precomp layer with motion blur off still
blurred masks; it now takes the gate (`masks::MaskBlur`) and the comp's Samples Per Frame
(four in Draft) instead of a fixed eight.
- Effects that read the shutter (`EffectEnv::shutter`) get it only when the layer is motion
blurred in this render.
- Advanced 3D layers follow the precomp layers' Motion Blur switches too.
- The layer cache key of a layer with masks or effects includes whether it is blurred and the
comp's shutter and samples, so a buffer blurred for the viewer is never reused by a render
with motion blur off.

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).

Depth of field in Advanced 3D comps uses the camera's iris (Fast Rectangle, Triangle to
Decagon, rotation, roundness, aspect, diffraction fringe) and highlight gain/threshold/
saturation through the Classic 3D bokeh kernel. Collapsed precomps in an Advanced 3D comp
add their nested layers as real geometry (meshes, extrusions, cards) lit by the parent;
2D collapsed precomps draw nested 3D layers with the parent's renderer. Text and shape
strokes extrude as bevelled meshes stacked in paint order (model extrude_stacked).

Planes prepared for the GPU carry their depth of field (padding, radius map, levels) and the
bokeh_boost / bokeh_prefix / bokeh_gather kernels blur them where they are drawn, with the CPU's
spans; GPU-vs-CPU agreement tests for iris shapes, highlights, fringe, Fast Rectangle, tilted
planes and a 2D layer with a 3D track matte.

Reconciled with main's keyframe labels (same Keyframe::label field; keys.setLabel and
keys.selectLabelGroup from main are kept, M14.5's duplicates removed; Edit ▸ Label on
selected keys delegates to the label helper), proxies (RenderOpts::proxy next to
nested_switches/draft_shadows), offloaded renders (Work carries nested_switches), wasm
