- 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.

- Properties panel (panels/properties.rs): Layer Transform with keyframe navigator
or stopwatch, AE value formatting (integers, %, Nx+N° rotation), linked Scale,
Reset; Text (font/style/size/leading/tracking/stroke, fill/stroke toggles);
Paragraph (7 alignments); Text Animation > Add Animator; scrolling.
- Tabs name what they show: Composition <comp>, <comp> timeline, Effect
Controls <layer>, Properties: <layer>.
- Default workspace: full-height right column, Preview over Properties.
- engine: time.go nextKey/prevKey accept prop uid; layer.setText supports all
seven justify modes, applyFill/applyStroke and Auto leading (fixes the
Paragraph 'justify' button mapping to Justify All).
- examples/snapshot: render the real UI headless (egui_kittest + wgpu) with
scripted control-channel steps.

Adds 105 effects in new modules (keying, matte, channel, blur2, color2, stylize2, noise, generate2, distort2, perspective, transition, utility) plus shared plane/morphology/guided-filter helpers in util.rs, with 96 new unit tests.
