  The regional service endpoint (cloudshell.us-east-1.amazonaws.com) is a
  SigV4-authenticated AWS API host and returns 403 for all unauthenticated
  /.well-known/ probes. The docs host (docs.aws.amazon.com) has no
  /.well-known/ discovery surface. Only the corporate host aws.amazon.com
  serves an RFC 9116 security.txt.
