notes:
- >-
  Extended on 2026-07-25 beyond the script's apis.yml-derived host list to cover
  the four other live Marshmallow hosts (auth., api., account., docs.), each
  probed directly over TLS and HTTP HEAD.
- >-
  HSTS is enforced on the two hosts that handle user credentials
  (auth., account.) but not on www., api. or docs.
- No CAA records and no DNSSEC on marshmallow.com; SPF present and DMARC at p=reject.
- No RFC 9116 security.txt is published on any host (see well-known/marshmallow-well-known.yml).
