Reaching this at ops.alphamethodx.com confirms the subdomain
resolves to its own folder independently of the apex rewrite.
The negative test is alphamethodx.com/ops/, which must return
404. An internal console reachable from the public marketing domain is
worse here than it is for the app.
Try /some/deep/route to confirm the SPA fallback returns this page rather than a 404.
