Why it matters

Every interactive element must be reachable and usable with just a keyboard. This includes navigation, forms, modals, menus, and custom controls. Follow established patterns from WAI-ARIA to ensure consistency and predictability.

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.
