    The Melius REST API. Authenticate with an API key as a bearer token
    (`Authorization: Bearer mel_...`) and select the team to act on with the
    `x-team-id` header. Generations run through the same node + run pipeline as
    the app: create a node on a canvas, start a run, poll the run, then read the
    resulting version asset.
