  note: The Buk Asistencia API runs on a separate, unhardened domain with no SPF, no DMARC, no CAA
    and no DNSSEC.
findings:
- buk.cl serves HSTS with a one-year max-age on www and a two-year max-age on tenant hosts; TLS 1.3
  throughout.
- buk.cl publishes SPF and a DMARC record at p=quarantine (not reject).
- No CAA record on buk.cl or ctrlit.cl; DNSSEC is not enabled on either.
- The Buk Asistencia API hosts (app.ctrlit.cl, app2.ctrlit.cl) send no HSTS header and sit on ctrlit.cl,
  a domain with no SPF, DMARC, CAA or DNSSEC.
