Checks for large GIFs that could be converted to video


Rule ID	`perf/animated-content`
Category	Performance
Scope	Per-page
Severity	warning
Weight	4/10

Solution

Convert large animated GIFs to video formats (MP4, WebM) for 50-90% smaller files. Use <video autoplay loop muted playsinline> for GIF-like behavior. Tools: ffmpeg, gif2webm, or Cloudinary can automate conversion. Modern video codecs are far more efficient than GIF for animation.
