Why it matters

Spellcheck is helpful for prose content but annoying for technical input. Email addresses, usernames, codes, and similar fields should have spellcheck="false" to prevent red squiggly underlines on valid input.

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.
