Beat-Driven UI Animation Workflow

A UI animation production workflow: the core rule is every frame is a pure function of time. From selecting royalty-free music around 120 BPM and providing 8–12 interface states, to a single-file HTML using seek(t) to compute styles, closed-form springs, beat-aligned sound effects, and frame-by-frame checking per beat before final rendering, the result is roughly 14 seconds. Perfect for learning to code UI animations and showcasing design work.
