proof-required

A problem type of the ckrets.ai API, answered with 401. The answer is application/problem+json (RFC 9457) with type https://ckrets.ai/problems/proof-required, title, status, detail and requestId. Branch on type, never on title.

#401: prove who you are

A box needs a proof you did not send or that was wrong (result: "wrong" counts an attempt; the body says how many are left and the cooldown); a 403 with this type is a failed Turnstile check: solve it again and send the fresh token.
