segment_value treated any non-Linear in-side of the next key as Bezier,
so a key set to Hold (KeyframeInterpolationType.HOLD, add_keyframe
"interpolation": "hold", or the Keyframe Interpolation dialog, which set
both sides) turned the linear segment into it into an ease-in with the
default ease: 0 -> 100 over 2 s read 27.0 instead of 25 at 0.5 s. Hold
only affects what follows the key, which the out side already handles.
The Graph Editor and the Lottie exporter already treat a Hold in-side as
linear, so exports didn't match the preview either.

CharStyle/TextDoc variations (layer.setText variations), shaped with harfrust instances so
advances follow HVAR/gvar, outlines drawn at the design-space position, animator deltas relative
to the style's values, Character panel Variable Font Axes fields (character.axis.<tag>).

Reconciled with main's keyframe labels (same Keyframe::label field; keys.setLabel and
keys.selectLabelGroup from main are kept, M14.5's duplicates removed; Edit ▸ Label on
selected keys delegates to the label helper), proxies (RenderOpts::proxy next to
nested_switches/draft_shadows), offloaded renders (Work carries nested_switches), wasm
audio pump (preview mix rate), variable font axes and mask feather points.

Text: vertical type turns Roman characters on their side (CJK stays
upright) unless Standard Vertical Roman Alignment is on; Tate-Chu-Yoko sets
selected characters horizontally in a one-em cell of the column (layer.setText
tateChuYoko / verticalRomanUpright, Character panel toggles). A Left-to-Right
paragraph is now forced LTR instead of auto-detected. The editing caret follows
animators and text on a path (render::text::caret_maps). Lottie export writes
per-character style runs as index-unit range animators.

Interface: Timeline outline columns wider than the pane scroll horizontally
(Shift+wheel/trackpad, scroll bar above the footer; headers clipped); the
Project panel's optional columns scroll under the frozen Name/Label columns.
ANM-1: keyframe colour labels (keys.setLabel, Label submenu, tinted key
icons) and Edit > Select Keyframe Label Group on selected/all layers and
visible keyframes (keys.selectLabelGroup replaces the stub). Alt-drag time
scaling of key groups already existed.

Shapes (SHP-2): Stroke Taper (pixels/percent start/end length, width, ease) and
Wave (amount, pixels/cycles, wavelength, phase) rendered as a variable-width
outline; Dash 2/Gap 2/Dash 3/Gap 3 (shape.dashes.add/remove, timeline +/-
buttons); radial gradient Highlight Length/Angle as a focal gradient.
Masks (MSK-1): mask feather points on the Mask Path (mask.featherPoint.*,
Mask Feather tool add/drag), per-point signed radius and tension, rendered
from the signed distance to the path; carried through vertex edits.
Motion blur (LYR-10): Adaptive Sample Limit comp setting; 2D layers take one
sample per pixel of shutter travel between Samples Per Frame and the limit.

TextDoc gains character style runs (font, size, colours, tracking, leading,
baseline shift, h/v scale, tsume, faux styles, caps, super/subscript, kerning
metrics/optical/manual, ligatures) and per-paragraph settings (justification
with last-line modes, indents, space before/after, direction, composer,
hanging punctuation), serde-compatible with single-style documents. Layout
handles mixed runs on a line (shared baseline, largest leading), every-line
composer, editing geometry (carets, hit testing, selection quads) and basic
vertical type. Renderer colours per run. Expressions get the sourceText style
API (style, getStyleAt, createStyle, setters with character ranges).

Engine (all commands with undo/redo + tests in engine/src/tests_timeline.rs):
- keys.copy/paste (Edit Copy/Cut/Paste route to keys when keys are selected;
relative timing kept, paste at CTI, cross-property paste of same type),
keys.selectAll (Cmd+Alt+A), keys.nudge* (Alt+Arrow, Alt+Shift+Arrow),
keys.set / keys.setEase (graph editor drags), keys.info (dialog data),
keys.timeReverse; keys.interpolation gains continuous/auto Bezier, spatial
interpolation and roving; keys.velocity takes per-dimension values and
Continuous.
- Roving keys (keyframe::retime_roving): constant speed along the motion path.
- Layer > Time: layer.timeStretch (percent|duration, hold in/current/out),
layer.timeReverse (Cmd+Alt+R), layer.enableTimeRemap (Cmd+Alt+T),
layer.freezeFrame, layer.freezeOnLastFrame; render uses Time Remap as the
source time for precomp/footage layers.
- prop.separateDimensions (X/Y/Z Position; prop.set on Position writes them).
- layer.setParent compensates so the layer stays in place (compensate:false
to opt out).
- prop.pickWhip writes AE-style reference expressions (thisComp.layer(..),
effect(..)(..), mask(..).maskFeather, temp=…;[temp,temp], …[0]).
- prop.setExpression: syntax errors keep the text but disable the expression.
- expr: arrays of properties returned by an expression are resolved.
UI: Keyframe Velocity, Keyframe Interpolation and Time Stretch dialogs;
Graph Editor (value + speed graphs, draggable keys and Bezier/influence
handles, auto-zoom, fit, show selected, separate dimensions, hold/linear/
auto Bezier/Easy Ease buttons); key + layer context menus. Clears the
workspace clippy -D warnings failures.
