Why it matters

Don't block password managers or prevent pasting in password/2FA code fields. Use appropriate autocomplete values (current-password, new-password, one-time-code) to help password managers function correctly.

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.
