uniform_parent_pose took the Y angle from asin, which loses precision within about 1e-6 degrees of
+-90. The Y angle now comes from atan2 on cos(Y), as the X and Z angles already do. The gimbal
branch and the principal-range output are unchanged.
A new test parents a static Orientation with Y 1e-6 degrees off gimbal lock under a uniform
parent. Its largest corner displacement was 3.3e-8 px before this change and 1.5e-14 px after.

The layer bar Quick Offset was followed and ended in its row's code, and
rows out of view aren't drawn. Released with its row scrolled away, it
stayed active: the next drag of that bar, even a plain one, ran as a
Quick Offset from the old origin, into the old undo step.
Like the key drag, it now follows the pointer below the rows and ends
when the button is released, wherever the bar's row is.
Test: a_quick_offset_released_off_screen_ends (release with the row
scrolled away; a plain drag after it moves both layers together as its
own undo step; fails before).
keys.quickOffset and keys.move stored the drag's new total before the
edit ran. When the edit refused the step (keys.quickOffset with a key
landing past the end of time), the project stayed as it was but the
total kept the refused delta, and with incremental steps (merge without
fromStart) the next step moved by it too.
The drag state is now stored only after the edit applies.
Test: a_refused_step_does_not_count_towards_the_drag (+1 s, a refused
step, -1 s: the keys end where they started; fails before: the last key
ends near the end of time).
keys.move and the nudges snapped each key's destination to the nearest
frame, so moving keys a Quick Offset had staggered onto subframes put
them back on frames: four keys at 0, 1/3, 2/3 and 1 frame, moved one
frame, came out at 1, 1, 2 and 2. Layer bars kept theirs, because
layer.timing snaps the move, not the times.
The move is now rounded to whole frames and every key translated by it.
layer_shift turns a comp-time move into a layer-time move through the
layer's start and stretch (reversed too) without a round trip through
comp time; keys.quickOffset uses it as well.
Test: moving_staggered_keys_keeps_their_subframe_spacing (Quick Offset,
then keys.move and keys.nudgeForward; fails before: 1/3 frame lands on
a frame).
prop.reset cleared every keyframe before setting the default value. As in
After Effects (and as effect.reset already does for effect parameters), an
animated property now keeps its keyframes and gets the default as a key at
the current time; a static property just takes the default. The expression
is still removed.

In After Effects a marquee selection staggers in the comp's layer order,
not in the direction the box was drawn. A Shift-click range of layer
bars and a box of keys already come out top layer first; this test makes
both with the pointer (the range from the bottom layer up, the box from
the bottom right to the top left) and checks the Quick Offset that
follows: the top layer stays and the bottom one moves the whole delta.
Validate saved stroke frames against the current layer limits before clamping a span edit. Keep project and undo state intact when trimming has left strokes outside the layer.

The Chinese UI fallback was chosen by probing 文, which Japanese faces
cover too. Fallback takes a face already loaded first, so after the
English interface had loaded a Japanese face for kana, switching to
Simplified Chinese reused it, and the simplified-only hanzi (选, 删,
层, 设, 页 ...) drew as boxes. A Simplified Chinese interface now probes
页, as wordcraft does for its interface font (storytold/wordcraft#248).
Ctrl/Cmd+Alt dragging a selected layer bar or a selected key now runs a
Quick Offset (layer.quickOffset / keys.quickOffset with fromStart, one
undo step). The mode is chosen when the drag starts and needs at least
two unlocked layers; the last selected layer moves by whole frames with
the pointer. A readout by the pointer shows the Total Offset and the
offset Per Layer, translated.
A plain drag still moves the selection together, Alt alone still scales
a key group in time (it now leaves Ctrl/Cmd+Alt to Quick Offset), and
Ctrl/Cmd+Alt+click still toggles Hold. The key drag's readout is drawn
by a shared drag_tip. Keys also register timeline.keyAt.<uid>.<ticks>,
exact where keys on subframes can share a frame.
Tests (ui_quick_offset): staggering layer bars in selection order and
keys per layer, one undo each; plain drags and Alt scaling unchanged; the
readout while dragging.
After Effects 25.4's Quick Offset staggers selected layers, or each
layer's selected keyframes, in the order they were selected: the first
stays, the last moves by the drag and the ones between by equal steps,
landing on subframes.
layer.quickOffset {delta, layers?} moves each layer's start, in and out
point by total * i / (n - 1), worked out once in ticks with integer
arithmetic, so 1 frame over 4 layers gives 0, 1/3, 2/3 and 1 frame
exactly. keys.quickOffset {delta} does the same per layer for the
selected keys, the layers in the order their first key was selected;
every selected key of a layer, across its properties, moves by that
layer's comp-time offset through its start and stretch (reversed too),
keeping values, interpolation, easing and labels. Locked layers are
skipped and at least two layers are needed. With merge and fromStart,
delta is the whole drag and each step starts again from before it, so
the drag is one undo step and a key passed over survives. A delta or a
destination out of the range of times is an error, not a clamped move.
Docs: agents.md; architecture.md notes Quick Offset as the exception to
times snapping to frames.
keys.move (and nudging) rebuilt the key selection in layer and property
order, so the order the keys were selected in was lost after a move. A
Quick Offset that follows staggers layers in that order (#1012).
The move now goes through move_key_refs, which maps each selected key to
its new time and returns the selection in its original order, with the
same collisions (a key landing on another replaces it), roving retiming
and locked-layer handling as before. key_gesture is the drag-step logic
(start again from the keys and project as they were before the drag)
split out of shift_keys so other key drags can share it.
Test: moving_keys_keeps_the_selection_order (fails before: the keys come
back sorted by layer).
The 2^28 pixel limit applied per image; one composite or layer decode kept
the ZIP output, a Vec<f32> per channel and the result alive together, and the
bake size came from the file's quad. A decode now charges every buffer
against a byte budget (4 GiB, 1 GiB on 32-bit), checks its whole expected peak
before allocating, writes channels straight into the result and returns an
error when over budget. Bakes are at most 4x the document across and 2^24
pixels.

The layer context menu gains an Effects submenu between Blending Mode and Arrange, mirroring the After Effects layer menu: the effect registry grouped by category (sorted), synced with the Effect menu; picking one applies it to the selected layers.
Raw channels are borrowed, ZIP planes are un-predicted in place in the inflated buffer,
the 32-bit un-predictor uses one scratch row, the layer mask tests the rect per row
instead of per pixel (and skips a constant factor of 1.0), and a placed-layer bake
solves the quad once and hoists per-triangle invariants. Output is bit-identical;
tests compare against the replaced implementations and count the avoided work.

Psd::parse drops the layers, records Psd::warnings and keeps the header and
merged image; the importer then imports the flattened image as one layer and
reports 'Layers could not be read'. Header damage and a missing merged image
stay hard errors.

One decode_plane for raw/RLE/ZIP (decode_channel and composite), placed::eight and
quad_from for the SoLd/PlLd transforms, the writer's big-endian and UTF-16 helpers

Psd::tree flattens groups nested deeper than MAX_GROUP_DEPTH into their depth-64 parent, keeping every layer, so the importer recursion and the tree's Drop/Clone/PartialEq are bounded. The import result reports how many groups were flattened.

A colour pick clicked in the Composition panel before the viewer had a frame
(still rendering on a background thread, or a readback pending) sampled nothing
but was used up, leaving the colour unchanged. The click now leaves the
eyedropper armed, as the text colour eyedropper already does.
timeline_colour_eyedropper_samples_the_comp clicked without waiting for the
frame and hit this in about one run in four; it now waits for the frame.

On Windows $.fileName is the full path with backslashes, so split('/') returned the whole path
and includes_are_inlined_relative_to_the_script failed. The test now takes the last part after a
backslash and then after a slash, with plain string splits: a regex split did not split the path
in the script engine.

CameraLayer gets the transform and camera-options shortcuts (position, xRotation, zoom...) that AVLayer already had, and Convert Expression to Keyframes run without a property converts the selected ones, as app.executeCommand does it.
The handle was filled with the colour of its own track (both the field
background), so it only showed while hovered or dragged. It now takes the text
colour, in every scroll area.

The floating group's title strip used the same id as its Area's own
background widget, and the Area was shifted back into the window while
the group's rect kept moving, so the two no longer overlapped and egui
painted "Double use of widget ID" over the panel. The strip has its own
id and the group is drawn where its rect says.

The editor's content was a little taller than its dialog, so the outer scroll
area clipped the OK button and its scrollbar covered the right edge. The dialog
now has no outer scroll area: the command list takes whatever height is left,
so the button row always fits, in small windows too.

The attach point's 12 px grab area sat on top of the feature region and is tested first. Zoomed out, a default feature region is smaller than that on screen, so every press inside it moved the attach point instead of the point. Inside the feature region the attach point now grabs only the region's inner half.
fallback_for tried every face that was already loaded before the usual
families of the character's script. Which faces are loaded depends on
every earlier lookup. On macOS, /Library/Fonts/Arial Unicode.ttf makes
Arial Unicode MS the first face in the scan, and it covers every script
that has usual families except Sinhala. The variable font search loads
it, and so does a fallback for a character that it covers and the
bundled faces and the usual families lack, such as the Simplified
Chinese 们. After that, Hebrew, Arabic, Indic, Thai and CJK text in a
Latin family fell back to Arial Unicode MS instead of Tahoma, Kohinoor
Devanagari, Tamil Sangam MN, Hiragino Sans or Apple SD Gothic Neo. In
the effectcraft-text unit tests,
other_scripts_fall_back_to_a_plain_system_family and
cjk_falls_back_to_a_system_family failed in 7 of 100 runs on a Mac, and
in 24 of 100 while other builds were running, depending on which faces
the other tests had loaded.
The usual families now come right after the bundled faces. family_faces
lists the installed faces of the script's families in the order they
are tried, each in the preferred face's style. The list is cached per
script and preferred face, and adding faces or changing the CJK locale
clears it. Faces that are already loaded come next, then the per-block
cache of the search over every installed font, then the search itself,
as before. A search result made for another character of the block (an
Armenian character next to Hebrew, Lao next to Thai, or a character
that no face covers) is no longer used for a character that a usual
family covers.
tests/script_fallback.rs runs in a test binary of its own. It records
the fallback for eight characters of those scripts, looks up U+0590,
Armenian and Lao and runs the variable font search, and checks that the
eight get the same faces again. It also checks that U+08A4, which on
macOS only faces outside the Arabic list cover, keeps its face after a
lookup of U+0870, which no face covers.
Problem: the built-in animation preset library had no Backgrounds category
(gap 7: 31 presets against After Effects' 621).
Fix: 23 original Backgrounds presets in crates/engine/presets/backgrounds.json,
built from our own generator, noise, colour and stylize effects: Soft Gradient
Drift, Aurora Veil, Slow Fog, Cloud Bank, Dark Smoke, Ember Haze, Magma Flow,
Ice Flow, Pastel Plasma, Cell Drift, Crystal Facets, Hex Mosaic, Mirrored Silk,
Water Caustics, Blueprint Grid, Checker Scroll, Scrolling Stripes, Pulse Rings,
Bokeh Drift, Spotlight Floor, Dawn Sky, Sweeping Light, Grainy Wash.
The preset format gains `expr` (an expression per property, so backgrounds keep
moving for the whole layer) and point parameters written as fractions of the
layer size. Effects & Presets lists them under * Animation Presets > Backgrounds.
Tests: catalogue uniqueness and categories, apply/undo/redo of every preset
(engine), render of every preset with the expression engine: finite,
non-flat, deterministic, moving (host), panel listing and apply (ui-egui).
Sidecar, ATTRIBUTION.md, gaps.md row 7 and effects-parity.md updated.

Undoes the 800 px Project Settings width from #980: the form is back at the
shared 480 px.
A form's choice popup keeps its 240 px column and ends a long choice (a GPU

Only the fields scroll, and only vertically; OK and Cancel sit under the

A vertex under or beside a box handle lost the press to the handle (the handle reaches 9 points, the vertex 6), the resize cursor showed over it, and the handles were painted over the vertex markers. Vertex reach now matches the handle's wherever one is in range, the cursor stays a pointer, and markers are drawn last.

The media layer keys decoded frames by path, and nothing dropped them when a
new project (or a new import) named a file that another app had overwritten
since, so a same-size overwrite showed the old pixels. Importing footage and
replacing the project now make the media layer and the layer cache let go of
the files involved.
