## Install

<InstallCommand command="npx hyperframes add keyframe-scrub-stack" />

That writes one file: `compositions/components/keyframe-scrub-stack.html`.

## Source

<Accordion title={`keyframe-scrub-stack.html`}>
  ```html theme={null}
  <!--
    Keyframe Scrub Stack - advanced HyperFrames primitive.

    This is intentionally seekable: drive it from a paused GSAP timeline.
    MotionPath examples require GSAP MotionPathPlugin. Three.js examples expose
    a render(progress) adapter instead of a free-running requestAnimationFrame loop.
