AI coding tools have gotten very good at motion. Ask for a landing page and you get parallax heroes, staggered reveals, spring physics on every card. It looks great in the demo.
Here's what it almost never ships with: a prefers-reduced-motion path.
Why this is a real problem, not a checkbox
Vestibular disorders are common. For the people who have them, large parallax movement, zooming, and spinning UI can trigger dizziness, nausea, and migraines. That's why the media query exists, and why WCAG has two success criteria aimed squarely at this:
WCAG 2.2.2 (Pause, Stop, Hide) — Level A. Anything that moves automatically for more than 5 seconds needs a way to pause, stop, or hide it. Level A means baseline, not aspirational.
