Layer Styles (Drop Shadow, Inner Shadow, Outer/Inner Glow, Bevel and Emboss, Satin,
Color/Gradient Overlay, Stroke) and Blending Options (Global Light, Fill Opacity, R/G/B,
Knockout, Blend Interior Styles as Group) as a layerStyles property group with AE names,
order and defaults. Rendered in layer space after effects (exterior passes composite with
their own blend modes below the body), cached per pass, scaled with render resolution.
Commands layer.style.* (menu Layer > Layer Styles), Global Light shared per comp, timeline
eye switches.

- 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.
