Transition Sequences
For choreographing multi-step animations like page transitions, modals, or onboarding flows where timing matters. The skill applies Disney's 12 principles to sequences, focusing on staggered starts (50-100ms offsets), 30-50% step overlap, and keeping total duration under 800ms for functional UI. You get concrete timing tables for common patterns (tab changes at 300ms, dramatic reveals at 1000-1500ms) plus formulas for calculating stagger delays. The overlap math is the useful part here since most developers either run everything simultaneously or leave awkward gaps. Includes the mandatory prefers-reduced-motion reminder to skip sequences entirely.

Transition Sequence Animations
Apply Disney's 12 principles to choreographed multi-step motion.
Principle Application
Squash & Stretch: Each element in sequence can compress/expand independently for organic feel.
Anticipation: Sequence starts with a setup phase. Brief pause or gather before motion begins.
Staging: Direct attention through the sequence. Most important element animates first or last.
Straight Ahead vs Pose-to-Pose: Plan keyframes for each step. Map the entire sequence before implementing.
Follow Through & Overlapping: Elements don't move in unison. Stagger starts by 50-100ms. Let motion cascade.
Slow In/Slow Out: Each step eases. The sequence overall should ease too - faster middle, slower ends.
Arcs: Transitions across space follow arcs. Page sliding left curves slightly, not linear slide.
Secondary Action: Primary transition + secondary details. Page slides while elements within fade/scale.
Timing:
- Step overlap: 30-50% of previous step's duration
- Total sequence: 300-800ms for UI, up to 1500ms for dramatic
- Gap between steps: 0-100ms (overlap preferred)
