summary:
  note: 'No rate limits are documented - 51offer publishes no developer documentation at all - and none are signalled
    at runtime. Live 200 responses carried no RateLimit-*, X-RateLimit-* or Retry-After header, and no 429 was observed.
    An honest zero: nothing published, nothing signalled.'
