Why it matters

WCAG 2.2.2 Level A requires that users can pause, stop, or hide moving content. This prevents distraction for users with attention disorders and reduces seizure risk. Loading indicators and progress bars are exempt as they provide essential feedback.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
