Add Per-Corner Roundness to Rectangle Path: a checkbox (off by default) and four Pixels properties (top-left, top-right, bottom-right, bottom-left). New rectangles initialise the four values from their Roundness, so ticking the box keeps the shape; the radii are animatable and expression-driven.\n\nrect_radii() builds the path clockwise from the top-left with kappa quarter-circle arcs. Overlapping radii scale down like CSS border-radius; negative and non-finite radii are square; rect() delegates to it, so uniform roundness clamps to half the shorter side as before.\n\nLottie rc has one r: four equal static radii export as that value; mixed or animated radii export roundness 0 with a warning. Import puts r into the four per-corner values so ticking the box on an imported rectangle keeps the shape.\n\nTests: path geometry and clamping, rendered per-corner pixels, Lottie equal/mixed/checkbox-off export.
#2410's dependency walk for a soloed 3D model was written before
reads_other_times took the effect count; it asks about all effects (None),
as the other walks do.

Text strokes were always drawn with round joins. The document gets a
Line Join (`lineJoin: miter|round|bevel` in layer.setText / newText),
Miter for new text as in After Effects, Round for documents saved before
it so their look is kept. The 2D and Advanced 3D (extruded) text strokes
use it, expressions' style copies carry it, and the Character panel has
Miter / Round / Bevel buttons under the stroke width.

Carry property, Font and Media Replacement overrides into the collapsed nested EvalCtx so nested layers render beyond the precomp frame instead of falling back to a clipped, flattened image. Key the layer cache on instance overrides to keep distinct collapsed instances isolated.
The referenced model's solo render goes through the comp camera: its
depth of field (focus, aperture, iris, highlights) blurs it, none of
which is in the projection matrix — the evaluated Dof is hashed in now
(CodeRabbit, review of #2410).
A model with an animation clip selected is posed at its layer time
(Animation Speed and Looping are static and hashed): the layer time is
folded into the key, so every time is its own entry. A model without a
clip keeps one key across times, as before.
An Environment light's image lights Advanced 3D models, and its source
can be any layer's render (or any environment layer) — too open-ended
to hash: while one is on, the read is not cached. Each is covered by a
render test.
Conflicts were main's new code next to this branch's additions; both kept:
- crates/effects/src/lib.rs: main's Buf::pad_sides stays as main wrote it
(Transform's transform_grow bounds that padding itself); Buf::pad keeps
this branch's effective-pad clamp.
- crates/raster/src/lib.rs: main's quantize_px/round_half_up and this
branch's MAX_PADDED_SIDE (still equal to limits::MAX_SIZE on main).
CC Composite stays After Effects-pure: its Layer parameter is gone, so
parameter indices match AE again (scripts and expressions that address
parameters by index). The model reference lives in its own effect,
ec.3d.instance3d (3D Channel, CPU, one layer parameter), which replaces
the layer's pixels with the referenced layer's render — alpha included.
A referenced model's solo render is now hashed into the owner's cache key
instead of declining the entry (Bflat, review of #2410): the layer, its
animated values and transform, the mesh item, the comp camera and lights,
draft 3D, the renderer setting and the in/out gate. Covered by a render
test: the copy is cached, served on the second render, and re-rendered
when the camera pans or the model leaves its in/out range.
- add_environment takes the evaluated light (&EnvLight) instead of nine
loose parameters — strict clippy (#2496) denies too_many_arguments.
- The Environment light's shadow map moves into env_shadow_map so
shadow_maps stays under the cognitive-complexity limit.
- tests/it/ui_env_light_repro.rs deleted: it duplicated ui_env_light_gpu
and the engine tests, and polled with sleeps of up to 12 s.

The mixdown evaluated levels and effect parameters once per block, and export mixes WAV/AIFF
in one-second blocks, so a level fade became a staircase that changed once a second. Animated
Audio Levels are now evaluated on a 1 ms grid of comp samples and interpolated in dB between,
and animated per-sample effects (Stereo Mixer, Backwards) run in 1 ms pieces with their
parameters at each piece. The grid is aligned to comp sample indices, so the result still does
not depend on the block size.

wiggle_transform looks up its Transform group itself and returns when
the group is missing, so it takes seven parameters and no longer needs
the clippy::too_many_arguments allow.
Every undoable edit keeps the previous project for undo, so the comp it touches
is shared and Arc::make_mut deep-copies it: every layer and every keyframe. An
edit therefore costs time in proportion to the comp's size, and a script that
sets many keyframes in a big comp goes quadratic (a 1,600-layer build with
~100k sampled keys took ~45 minutes).
Comp::layers is now a Layers collection backed by Vec<Arc<Layer>>: copying the
stack copies pointers, and only the layer an edit changes is copied. The API
mirrors Vec<Layer>; serialized form is unchanged (a list of layers).
Comp::layer_mut and the iter_mut().filter/find call sites use find_mut /
iter_mut_where so they copy only the layers they actually change.
- prop.addKey in a 400-layer comp: 1.36 ms -> 0.16 ms per key (flat in comp size)
- the 1,600-layer script build: ~45 min -> 47 s, frames pixel-identical
- regression tests: an edit leaves the other layers shared with undo; layers
round-trip as a plain list

Resolve the Interpret Footage form against main's split into
interpret_footage_form and project_settings_form, keeping the Cineon
Settings fields and the pointUnits readback. Restore the Arc, rayon
prelude and cineon_frame imports that main's explicit use lists dropped.
