Stabilize browser suite CI route flows

   - detect when `BrowserRouteDriver` is opening the first routed page from the primed blank test page

+- [x] `Release Pipeline` run `24221639706` fails remotely in all four browser suites after commit `7983efe`
   Symptom:
   - `Shell` fails `11` tests, mostly while opening `/library`, plus two invalid learn/teleprompter missing-script flows and two onboarding route-changing clicks
   - `Studio` fails `6` tests, split between first-route `/library` boot, `go-live-back` hangs, and `StartRecording` click paths that stall on scheduled navigation waits
@@ -223,6 +223,10 @@ Tracked failing tests from the current baseline:
   - introduce a shared `NoWaitAfter` click helper for SPA route/state-changing controls and use it in the failing Shell, Studio, and Editor flows
   - retry page screenshot capture in the shared artifact helper
   - stop awaiting camera detach inside `GoLivePage` location-changing so route leaves are not blocked by cleanup
+  Result:
+  - local follow-up validation is fully green after hardening SPA route-changing clicks, library/settings route reload helpers, go-live back navigation, selected-program-source visibility checks, and the brittle teleprompter reverse-transition assertion
+  - targeted suite reruns passed with `Shell 51/51`, `Studio 38/38`, `Reader 168/168`, and `Editor 284/284`
+  - the required post-format solution verification passed with `1162/1162`
 - [x] `StandaloneAppFixture` shared-context creation still exposed accidental cross-test coupling
   Symptom:
   - the browser harness still defaulted `NewPageAsync()` to the shared-storage path, so any missing `additionalContext: true` quietly joined a shared browser context and became order-dependent under CI parallelism
