Mint a 7-day link that opens brandbooster.ai/creator-partnership with this creator's own details already in the chosen tier's form.

Behind a login, unlike the three intake routes: the caller is us, sending the link out, not the creator filling it in. prefilled_fields in the response says what we actually held, so whoever sends it can see how much the creator still has to type.

Screenshot proofs are never prefilled — those come in through the Google Form.

current_plan is the tier the creator already holds, for disabling that card and tagging it "Current Plan". It reads the creator's subscription, not Creator.plan — that column defaults to registered for all 24,000-odd scraped creators, so only a subscription row tells a real Registered signup apart from someone who never applied.
