The Tools bar's Snapping options menu (#265) offered per-feature
toggles (Edges, Corners, Centers, Anchor Points, Mask and Shape Path
Points) that After Effects' Snapping menu doesn't have. It now has the
two After Effects has:
- Snap Edges Extended (as before).
- Snap to Features in Collapsed Compositions and Text Layers: the
visible layers inside a precomp layer with Collapse Transformations
on are snap targets too, mapped into the outer comp (points always,
edge lines while the precomp layer is unrotated); a snap highlights
the precomp layer. Nested collapsed precomps are followed eight deep.
Every layer feature snaps again (corners, edge midpoints, centre,
anchor point, mask and shape path points); the snapping engine itself
is unchanged. `view.snappingOptions` takes `edgesExtended` and
`collapsedFeatures` (and `toggle` of either); the old keys are refused.
Test: collapsed_precomp_features_snap (fails before: no such option),
snapping_options_command_sets_and_toggles (the per-feature keys are
refused), snapping_options_pick_the_targets (AE behaviour kept: edges
extended or not, hidden layers, guides only), and the Snapping menu UI
test (only the two options are listed).

Dragging a layer already snapped its feature nearest the pointer to
other layers' edges, corners, centres, anchor points and path points
and to the comp's edges and centre, and Cmd/Ctrl held during the drag
already turned snapping on or off against the checkbox. What was
missing were After Effects' Snapping options beside the Tools bar's
checkbox. The new menu turns Snap Edges Extended off (a layer's edges
then snap only along the layer, not across the comp) and each feature
family (edges, corners, centres, anchor points, mask and shape path
points) on or off, for the dragged layer's snap features and for the
targets alike. Agents set them with view.snappingOptions.
Layers whose eye is off (or that a solo hides) are no longer snap
targets, mask and shape path points of the dragged layer snap too, and
while snapping is on the feature that snaps is boxed during the drag.
Test: layer_drag_snaps_to_other_layers_edges_ctrl_toggles_and_options_apply
(UI), snapping_options_pick_the_targets and
snapping_options_command_sets_and_toggles (engine).

The Pan Behind drag passed its layer to the snapper's exclude list, which
dropped all of that layer's targets: its corners, edge midpoints and centre
as well as the anchor being dragged. The layer's box doesn't move in comp
space while the anchor pans (Position compensates), so those points are
valid targets.
The engine's per-layer snap targets are now one function, layer_targets,
which can leave out the anchor point. The gesture records its layer's
targets without the anchor as the drag begins and passes them to the
snapper (snap_with) as extra targets.

- 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.

Composition viewer interaction parity with After Effects:
- Snapping (View > Snapping, the Tools bar checkbox, Cmd/Ctrl inverts while
dragging): layer edges, centres and anchor points, mask and shape-path
vertices, comp edges/centre, guides (Snap to Guides) and grid (Snap to
Grid), with highlighted target box / line / cross feedback. Pure maths in
engine::viewer (nearest target within tolerance, priority ties).
- Rulers (Cmd+R) with live pointer markers and a draggable zero point;
guides dragged out of the rulers, moved in the viewer, dragged off to
remove (view.moveGuide / view.removeGuide), lock respected; proportional
grid.
- Show Channel (RGB/Red/Green/Blue/Alpha/RGB Straight, Colorize), exposure
(+/- stops in linear light, reset), Take Snapshot (Shift+F5) with a stored
render and Show Snapshot (F5 held / button held), Fast Previews (Off,
Adaptive Resolution, Draft, Fast Draft, Wireframe), Resolution > Custom.
- Region of interest: drawn in the viewer; RenderOpts.roi renders only that
rectangle (crop of the full render, tested), Crop Comp to ROI uses it.
- Bottom bar in AE 2026 order ("136.1 %", "(Full)").
- Shape Pen (SHP-1): Pen on a shape layer / nothing selected draws Shape n
groups (Path 1, Stroke 1, Fill 1) via shape.newPath; the G slot cycles
Add / Delete / Convert Vertex and Mask Feather; mask.* vertex commands
work on shape paths; mask.insertVertex / mask.convertVertex; marquee
vertex selection, Alt-drag/click converts, double-click free transform
box (path.freeTransform on masks and shape paths).
- Motion paths (ANM-3): keyframe dots and spatial tangent handles, dragging
keys (keys.set) and tangents (keys.setSpatialTangents), parented layers.
