- Lumetri: HSL Secondary key/refine/correction with Show Mask, Hue vs Sat/Hue/Luma,
Luma vs Sat, Sat vs Sat and per-channel RGB curves, High Dynamic Range (HDR White /
Specular), Input LUT and Look (custom .cube + built-in looks).
- Hue/Saturation: Channel Control with Reds..Magentas ranges (range + fall-offs).
- Levels: Channel popup and Red/Green/Blue/Alpha controls; Curves: Channel parameter.
- catalog::param_shown: Effect Controls shows only what a popup selects.
- Timewarp Pixel Motion: block-matching flow (raster::flow::block_flow_window) with
Vector Detail, Smoothing, Error Threshold, Block Size, Weighting, Correct Luminance,
Filtering, Build From One Image; Matte Layer/Channel, Warp Layer, Show, Source Crops.
- GPU falls back to CPU when channel/range controls are used.

Aux-channel model (effectcraft_raster::channels3d: depth, object/material
ID, normals, UV, coverage, Cryptomatte ranks + manifests, MurmurHash3);
EffectHost::aux; multi-layer OpenEXR channels via the exr crate
(FootageSource::aux); the compositor's depth / layer-ID / Cryptomatte pass
(Renderer::comp_aux) so the effects work on precomps of 3D comps.

Frame Mix and Pixel Motion for footage and precomp layers when the layer's
Frame Blending switch and the comp's Enable Frame Blending are on and the
source time falls between source frames (rate conform, time stretch, time
remap). Exact frame positions from tick arithmetic. Pixel Motion is a
hierarchical block-matching optical flow (SAD search, sub-pixel parabola
fit, vector median) with a bidirectional warp-blend (raster::flow). Blended
footage frames are cached.

- render: LayerCache (content-keyed processed-layer cache: source -> masks ->
effects, keyed by a hash of the layer's non-transform props evaluated at the
frame time, solid item, switches, scale; time folded in for clock-driven
effects / wiggle paths). Static and transform-only layers render once;
edits only re-render the edited layer. Session + UI frame jobs share it.
- effects: TIME_DEPENDENT list + test that every clock-reading effect is listed.
- raster: affine composite fast path (per-row span clipping, unchecked interior
bilinear, integer-translation copies, inlined Normal blend), checked against
composite_warp_reference; box/Gaussian blur without transposes, two
ping-pong buffers; accumulate_warp so motion blur sums into one buffer
instead of one full-frame image per sub-sample.
- ui: viewer frame is urgent and jumps the prefetch queue; stale-revision jobs
are dropped; paused prefetch waits for the viewer frame; "Frame Render Time"
reports viewer frames only; parallel f32 -> Color32 conversion.
- cli: `frame --bench N` (per-layer/per-effect timings, wall + CPU time) and
`frame --bench-play N` (consecutive frames with/without the layer cache).
- tests: cache transparency (scrub, edits of values/keys/effects/masks/
solids/text/timing), hit/miss accounting, time-dependent effects, demo
cached == uncached, fast warp/blur/accumulate == reference.
