{{--
    Application Settings > Domains: what the two "DNS lookup" options can
    actually do on THIS server.

    Both providers run through the same redundancy ladder (dig over UDP/53,
    then DNS-over-HTTPS on 443), so a host without `dig` still verifies
    domains. Only when neither can run does verification pause - and then this
    block says exactly what is missing and offers to switch to a method that
    answers from here.
