@rougher-stuff/animation

Progress-driven animation controller shared by Rough.js and Rough Notation. The runtime supports play, pause, reverse, seek, cancellation, completion promises, event subscriptions, and normalized timelines. Manual seek() does not depend on browser layout or SVG DOM path metrics.

const animation = createAnimation({
  duration: 800,
  update(progress) {
    render(progress);
  },
});

animation.seek(0.4).play();
await animation.finished;
