notes: >-
  All Fortnox API, WebSocket, OAuth, and web hosts serve TLS 1.3 with GlobalSign
  OV certificates and enforce HSTS (max-age 31536000, includeSubdomains). The
  fortnox.se apex publishes SPF (-all), DMARC (p=quarantine), and a restrictive
  CAA allow-list. DNSSEC was not observed on the apex at probe time.
