  Inrupt publishes no request-rate limits and no rate-limit response headers on any surface. What it
  does publish are capacity and quota ceilings, several of which are deployment-configurable because
  ESS is customer-operated software rather than a metered public API. The reference page nominally
  reserved for this - https://docs.inrupt.com/ess/reference/limit-and-thresholds - is published with a
  heading and no body (probed 2026-08-23, HTTP 200, 303 bytes).
