✅ Served from the BACK-END (192.168.1.7)

If you are reading this over https://pdrmanagers.com, the front-end relayed your request to the back-end. This page lives on the back-end at 192.168.1.7:5001 — not on the front-end.

This is the target architecture: front-end = public relay, back-end = holds the app. The real ASP.NET app just swaps into this slot.
