  The API host is ukpowernetworks.opendatasoft.com — UK Power Networks' own subdomain running an
  Opendatasoft Explore deployment. It answers /.well-known/security.txt with an RFC 9116 document,
  but that document names the platform vendor (Opendatasoft) rather than UK Power Networks, which is
  recorded honestly below rather than restated as a UK Power Networks contact. The corporate host
  www.ukpowernetworks.co.uk sits behind Akamai and returns HTTP 403 to anonymous non-browser
  requests for every /.well-known/ path probed, so absence there is unproven rather than confirmed.
