        credential for REST/programmatic and headless integrations. Manage keys
        in Settings → API Keys. API keys do NOT authenticate the MCP endpoint

        Supabase-issued JWT used by the Oviond web app session. External API
        consumers should authenticate with an Oviond API key (ApiKeyAuth)
        instead.
