+Open [https://localhost/](https://localhost/) after `make up` (gateway), or the
+HTTPS URL printed by `make up-local`. Internal simulator port is `8080`; the lab
+UI is also on that host.
 
 The UI is a laboratory console for the **vSphere** simulator — not a vSphere Client
 replacement. It supports light and dark themes, catalog majors **6–9** (vSphere 7–8.0U2
 floors), request/response editing, history, and runtime contract apply.
