  notes: >-
    Photon secures its single GraphQL endpoint with OAuth2 client-credentials
    access tokens issued by Auth0. Tokens are presented as a Bearer token in the
    Authorization header. Two token shapes: machine-to-machine (backend, all
    actions except write:prescription) and user access tokens (frontend via
    Elements; only authorized providers receive write:prescription).
