SEO content brief builder

Everything in the brief comes from your inputs plus fixed editorial rules. No competitor page is fetched or copied, and the word range is a bound you set, not a number scraped from anyone else's article. The auto intent guess is a word list, not a model: it reads words like "buy" or "how" in the keyword, so a keyword with none of them defaults to informational. If that guess is wrong, pick the intent yourself and the brief follows it.
