A startup key (last, empty or demo) chooses the project the page opens on load. empty restores the last visit's project and otherwise starts blank, never with the demo; demo always opens the demo project; last, or no key, is the current behaviour. ?empty and ?demo still win. The config file is fetched once per page load and the service worker never caches it.
A missing or unusable curve no longer consumes the last value. The long form reads argument 5 and the short form argument 3, with the other arities falling back to linear interpolation. Adds the missing-curve and four-element-array cases reported in review.
- accept only four-element arrays for bezier(): extra values make the curve
malformed, so it falls back to linear like the other invalid forms (#1884);
- stop Newton on the estimated y error (f * dy/dx) instead of a residual in x
alone: near the endpoints dy/dx is in the thousands, so a 1e-9 residual in x
could still move the returned value;
- tests: a five-element curve is linear, and three steep curves match a
bisection reference within 1e-6.
Add the helper to the expression editor's completions (syntax highlighting and auto-complete) and to the Expression Language menu's Interpolation group, so accepting it inserts the call parentheses like linear/ease.
Add bezier(t, tMin, tMax, v1, v2, [x1, y1, x2, y2]) and the short bezier(t, v1, v2, curve) form: a CSS cubic-bezier easing curve solved with Newton-Raphson and a bisection fallback.
Scalars and arrays work like linear/ease; x1/x2 clamp to 0..1, y1/y2 may overshoot, t clamps to tMin..tMax, and a curve that is not four finite numbers falls back to linear instead of throwing.
Tests cover known curves (ease is [1/3, 0, 2/3, 1]), clamps, arrays, the short form, invalid curves and overshoot, plus two fuzz seeds.
Closes#1884.
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.
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.

Dither can round a colour byte up while alpha rounds down (colour = alpha = 100.25/255 gives
alpha 100, colour 101), breaking the premultiplied invariant. Clamp each dithered colour byte
to the written alpha byte.
Test: dithered_premultiplied_colour_never_exceeds_alpha.
Resolve the export tests' module list (banding and h264_gpu_yuv both stay). #1631's
yuv420_frame checked Render Settings Color Depth itself; that depth is now the project's
depth for the whole render, so the GPU YUV path is taken only for 8 bpc renders. Above
8 bpc frames take the RGBA path, which dithers, so H.264 exports don't band either.
Test: renders_above_8_bpc_skip_the_planes.
Per review: as in After Effects, the region of interest lies inside the comp, so each converted
ROI edge is clamped to [0, w] / [0, h] and the far edge never passes the near one. A hostile ROI
reaching far outside the frame can no longer pad it into a huge crop, the wide-frame case keeps
its full width, and the i64 widening is no longer needed (frame_size is back to main's code).
Tests: hostile quads give edges >= 0 and a frame between 1 x 1 and the frame size, and an ROI
covering more than the frame is the whole frame.
The CJK render test skipped wherever no Japanese face was installed, which
is every CI runner, and on a Mac it drew glyphs with or without the fix, so
it caught nothing. Replace it with a fallback-order test: fixture faces for
`Hiragino Sans` and `Hiragino Sans GB` show that a zh-hans Han lookup tries
the Chinese family first, that ja tries the Japanese one, and that a layout
gets Hiragino Sans GB. Synthetic fonts in an isolated child process keep it
independent of the host's fonts; with the Simplified list reverted it fails
on `[7]` against `[8, 7]`.
Delete `TEST_CJK_LOCALE`: the locale-mutating tests moved to an isolated
child process, so nothing used the lock and the test-only static failed
clippy's `-D warnings` gate.
Trim the documentation edits to the single docs/gaps.md gap-11 row: revert
the header and changelog edits in ROADMAP.md, docs/roadmap.md,
docs/localization-parity.md and docs/target-app-parity.md, and the gaps.md
header and changelog row, which conflict with other PRs.
Tests: cargo clippy -p effectcraft-text -p effectcraft-render --all-targets
-- -D warnings, cargo clippy --workspace --all-targets -- -D warnings,
cargo test -p effectcraft-text (79 lib), cargo test -p effectcraft-render
(264 passed, 1 ignored perf test), cargo fmt --all -- --check.
A shape's painted bounds can be tiny enough (a 1e-305 px rectangle) that
the fit scale overflows to infinity. Non-finite bounds are skipped and a
non-finite scale returns an error before anything is written, instead of
storing infinity in the document.

layer.transform's fit / fitWidth / fitHeight ops took the layer's size
from render::source_size, which returns (0, 0) for layers without a
source item — shapes and text — so the ops matched nothing and silently
did nothing, for the shortcut, the menu item and the command alike.
When the source size is empty and a fit op runs, the size falls back to
the layer's painted content bounds at the current time, and the anchor
goes to the bounds' centre: content bounds live in layer space, where a
shape is centred on the origin and text sits above its baseline, so
(w/2, h/2) would fill the frame but land off-centre. Reset and the
other ops keep the source size, so their defaults are unchanged.
The regression test asserts what the viewer shows — the painted bounds
mapped to comp space span [0, 0, 640, 360] after fit, and fitWidth
spans the width centred vertically — for a rect shape and a text layer.

Edit > Clear follows panel focus: with the Project panel focused it
redirects to project.delete, which removes the selection at once when
nothing uses it. With a text edit open, that deletes the composition
being typed into — the user is working in it — and undo restores the
item but not the active composition. During a text edit the redirect
stands down (Clear does nothing) and the Edit menu's Clear entry is
disabled, mirroring how Deselect All stands down in #2096.

Edit > Duplicate replaces the layer selection with the copies, but an
open in-canvas text edit stayed on the original layer: typing kept
editing a layer that was no longer selected. When the duplicate leaves
the edited layer deselected, end the edit the way #2096's Deselect All
does (text_edit::end_edit), in the command every caller — menu, shortcut,
MCP — dispatches through.
