Audit a live URL for motion-accessibility issues (WCAG 2.2.2 Pause, Stop, Hide and WCAG 2.3.3 Animation from Interactions). Use when asked to check a site's animations, reduced-motion support, autoplaying/looping motion, or "motion slop".

Part of motionspec
Author verified, reduced-motion-safe web animation with MotionSpec. Use when adding scroll, entrance, hover, or loop animation to a website or web app — instead of hand-writing GSAP or CSS keyframes, write a MotionSpec JSON spec, validate it, and compile deterministic code.
