  Two hosts serve a real RFC 9116 security.txt (api.lengow.io and the canonical my.lengow.io). Every other
  /.well-known/ path 404s on every host. Note the served security.txt carries an Expires value of
  2023-09-08, so the document is present but stale by RFC 9116's own freshness rule. www.lengow.com and
  my.lengow.io answer /.well-known/* misses with an HTML 404 page (not a soft-200), so nothing was
  mistaken for a document.
