  Open Platform developer host. www.xa.com returns real 404s for every document.
  open.xa.com is a Vue SPA whose server returns the HTML app shell (HTTP 200,
  text/html) for every unknown path, so its 200s are SPA fallbacks, not real
  documents - recorded as spa-fallback. No genuine well-known documents were
  found on either host.'
