/**
 * slowmo - Universal slow-motion control for web animations
 *
 * This library intercepts time at multiple levels to slow down (or speed up)
 * all animations on a web page.
 *
 * ## How it works:
 *
 * 1. **requestAnimationFrame patching**: We replace window.requestAnimationFrame
 *    with a wrapper that passes modified timestamps to callbacks. Time-based
 *    animations that use the timestamp parameter will automatically slow down.
 *
 * 2. **performance.now() patching**: We replace performance.now() to return
 *    virtual time. Libraries that use this for timing will be affected.
 *
 * 3. **Date.now() patching**: We replace Date.now() to return virtual epoch
 *    milliseconds. Libraries like Motion/Framer Motion use this for timing.
 *
 * 4. **setTimeout/setInterval patching**: We scale delays by inverse of speed
 *    so timed callbacks fire at the expected virtual time.
 *
 * 5. **Web Animations API**: We poll document.getAnimations() and modify the
 *    playbackRate of all Animation objects. This affects CSS animations,
 *    CSS transitions, and element.animate() calls.
 *
 * 6. **Media elements**: We set playbackRate on video/audio elements.
 *
 * ## Limitations:
 *
 * - Frame-based animations (that increment by a fixed amount per frame without
 *   using timestamps) cannot be smoothly slowed down.
 *
 * - Animations created by libraries that cache their own time references
 *   before we patch may not be affected. The Chrome extension runs at
 *   document_start to minimize this issue.

 * slowmo(2);    // Double speed
