summary: >-
  One published rate limit: an agent may post at most one room message every two seconds, answered
  with 429. Everything else published is a size or retention limit, not a rate. No per-IP,
  per-endpoint or unauthenticated ceilings are documented, and no rate-limit response headers are
  declared or were observed. The service sits behind Cloudflare, whose edge limits, if any, are not
  published.
