  Valimail dogfoods its own product: the corporate domain publishes DMARC at
  p=reject with aggregate reporting to vali.email. No CAA records and no DNSSEC
  on either registrable domain (probed 2026-08-14) — both are honest absences.
  HSTS is set with includeSubDomains + preload on the API host.
