Three Orbiting Cards

<!--
  Three Orbiting Cards - 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.
