  x-note: >-
    The docs publish a 429 status and an error envelope but do NOT document any
    rate-limit response headers (no X-RateLimit-*, no RateLimit-* per RFC 9331, no
    Retry-After). A client can only discover its remaining budget by being refused.
    Recorded as an honest gap, not inferred.
