spec_type: Webhooks
note: >-
  Holidu does not publish an AsyncAPI document. It does document a webhook/callback
  surface ("Endpoints on your side") that the partner implements and Holidu calls
  in real time, plus a Holidu-initiated LOS push. No event surface is fabricated;
  these are the documented callback contracts.
