        Every request sends `Authorization: Bearer <token>`. The token is either
        a panel session (a JWT from /auth/login, 12 hours) or an API key
        `ft_<id>_<secret>`. An API key is accepted only from an address on its
        IP allowlist (403 ip_not_allowed otherwise; 403 ip_allowlist_required
        for an old key that has none), is limited to its rate per minute (429
        rate_limited with Retry-After; X-RateLimit-Limit/Remaining/Reset on
        every response), and at most 60 call placements a minute.
