    Authentication:

    - Use `Authorization: Bearer <session-token>` for user-authenticated routes
    that require a Den session.

    - Use `x-api-key: <den-api-key>` for API-key-authenticated routes that
    accept organization API keys.

    - Public routes like health and documentation do not require authentication.


    Swagger tip: use the security schemes in the Authorize dialog to set either
    `bearerAuth` or `denApiKey` before trying protected endpoints.
