  FitStar Labs, Inc. is defunct — acquired by Fitbit on 2015-03-05 and wound down.
  The fitstar.com domain is still registered and actively administered (Google Cloud
  DNS, Google Workspace mail, Salesforce SPF include, CAA restricted to pki.goog),
  but it publishes NO A record and serves no web content, so there are no HTTPS/TLS
  or HSTS observations to record. Mail and DNS posture is recorded because it is real
  probed data; absence of web hosts is a valid, expected result.
