    Probed on every known Syllable host. syllable.ai, api.syllable.cloud and
    syllable.cloud all returned 404 for both /.well-known/agent-card.json and the
    legacy /.well-known/agent.json. Only the documentation host serves a card, and
    the card describes the documentation surface (url and provider both point at
    docs.syllable.ai), not the api.syllable.cloud platform API.

    The card passes the three structural checks (capabilities is an object,
    protocolVersion is present, skills is an array) and carries the optional
    preferredTransport, defaultInputModes and defaultOutputModes fields. It is graded
    flavored on one field-name deviation: it publishes supportedInterfaces where A2A
    1.0.0 specifies additionalInterfaces. protocolVersion is also "0.3" rather than a
    1.0.x value.
