A text animator's Tracking Amount is in pixels in After Effects 2026, not in
1/1000 em like the Character panel's tracking: Amount 30 on every character
adds 30 px between neighbours (half before, half after each) at 80 px and at
40 px. And a Subtract range selector over characters the first selector
leaves out keeps them at 0 instead of selecting them negatively. With both,
the EXPORTER's t8 layer D (Tracking 30 on characters 2-4 by index, Subtract
over the last 20 %) puts every glyph where AE does (it ended 88 px short,
1553 vs 1641; now 1641).
The "Tracking In" text preset animates 40 -> 0 px (was 400 -> 0 thousandths
of an em, about the same at 100 px text); Lottie export writes a style run's
tracking (1/1000 em) as pixels for its tracking animator, which Lottie
players add in pixels.

Problem: the built-in animation preset library had no Behaviors category
(gap 7: 54 presets against After Effects' 621).
Fix: 22 original Behaviors presets in crates/engine/presets/behaviors.json:
Soft Wiggle, Shake, Float, Sway, Orbit, Figure Eight, Bouncing Ball, Drift
Right, Drift Diagonal, Pendulum, Wobble, Spin Slow, Spin Fast, Pulse,
Heartbeat, Breathe, Rubber Band, Jitter Scale, Blink, Strobe, Flicker, Fade
Pulse. Each puts a time-based expression on one transform property or
opacity (no effects), built on the property's own value so it keeps running
for the layer's whole duration. Listed under * Animation Presets > Behaviors.
Sidecar, ATTRIBUTION.md, gaps.md row 7 and parity docs updated.

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.

Problem: EffectCraft shipped only 8 original text-animator presets against
After Effects' 621; there was no Transitions category (ranked gap #7).
Fix: an original preset library, crates/engine/presets/transitions.json
(23 presets on our own Transition effects and layer opacity: fades,
directional and diagonal wipes, clock and fan reveals, blinds and slats,
pixel/mosaic dissolves, card flips, CC grid, radial scale, line sweep and
jaws wipes; In and Out). New commands anim.applyBuiltinPreset (adds the
effects with values and keyframes from the current time, one undo step,
reports any path that doesn't fit) and anim.builtinPresets. Effects &
Presets lists them under * Animation Presets > Transitions; double-click
applies. Sidecar and ATTRIBUTION.md entry; gaps/effects-parity updated.
