  Vendia publishes no AsyncAPI document. Probed for one and found none; the event
  surface below is captured from the Vendia Notifications documentation instead, and
  the artifact is wired as `Webhooks`, not `AsyncAPI`. Nothing here is fabricated —
  payload fields are the ones Vendia names in its docs.
