  title: Canvas Medical Appointment Scheduling
  summary: Locate a patient, find a practitioner's schedule, search for a free slot, then book and confirm an appointment.
  description: >-
    A FHIR scheduling flow against the Canvas FHIR R4 API, following the Argonaut
    Scheduling pattern of Schedule -> Slot -> Appointment. The patient is located,
    the practitioner's Schedule is found, a free Slot is searched for, an
    Appointment is created against that slot, and the booked Appointment is read
    back to confirm. Every step inlines its request so the flow is self-contained.
