notes: No public Quaker Houghton API or developer documentation is published. The Events Calendar REST
  API on home.quakerhoughton.com answered a live anonymous GET (2026-09-17) with no X-RateLimit-*,
  RateLimit-* or Retry-After header; the only edge in front of it is Cloudflare (cf-ray, cf-cache-status).

  are governed by the enterprise integration agreement.
