#1510: Behaviors animation presets (22 original, expression-driven)
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. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
