Why it matters

Screen readers don't automatically announce dynamically added content. Use aria-live="polite" for non-urgent updates like toasts and validation messages. This ensures screen reader users are informed of changes without interrupting their current task.

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.
