  Two real documents served: a PGP-signed RFC 9116 security.txt at the opera.com
  apex (saved verbatim as opera-security.txt) and a real llms.txt at
  www.opera.com (saved verbatim as ../llms/opera-llms.txt). Everything else is
  a miss. IMPORTANT — ofa.adx.opera.com and ofp.adx.opera.com are single-page
  apps whose catch-all answers HTTP 200 with an HTML shell for EVERY
  /.well-known/* path; those 200s are recorded below as misses, not documents.
  cms-adx.op-mobile.opera.com 301s every path to a redirect page. No agent card
  was found on any host, at either the current or the legacy path.
