Why it matters

When the submit button is disabled before the user has tried to submit, they can't discover what's wrong with their form. Enable the button, let them click it, then show comprehensive validation feedback that guides them to fix all issues.

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.
