Build several genuinely different UI versions from a description, put them behind a visual picker, and choose one after flipping through them live.

Coordinate elements that animate together by choosing order, stagger and timing, so the group reads as one motion rather than a queue.

animation-performance gathers rules for diagnosing dropped frames, including animated shadows, large blur values, inherited CSS variables, and a busy main thread.

An interface animation workflow uses prototype to explore variants, animate to choose easing and timing, and then iterates on the selected design.
