summary: 'All six VIPKid / VIPTeacher hosts serve HTTPS with a valid certificate — the two Nuxt
  marketing hosts negotiate TLS 1.3, the four behind the Akamai/Tengine edge negotiate TLS 1.2 — but
  the wider domain posture is thin: not one host sets HSTS, none of the three registrable domains is
  DNSSEC-signed, none publishes a CAA record, and vipkid.com has SPF but no DMARC record at all.
  vipkid.com.cn (p=quarantine) and vipteacher.com (p=none) do publish DMARC. Absence of a record here
  is an observed fact, not a failed lookup.'
