• Pause periodic network updates in hidden tabs (asturksever, #1282).
• Report and guard browser visibility during Transit QA so hidden-page polling pauses cannot masquerade as playback regressions (asturksever, #1282).
• Require each live city to supply its own feed vehicles in Transit QA; retained vehicles cannot qualify another city (asturksever, #1282).
• Bound the Transit card-anchor probe by observed poll coverage instead of a fixed 20-second window (asturksever, #1282).
• Keep visible-page Transit probes focused through the browser testing API (asturksever, #1282).
• Add a real-browser regression gate for hidden-tab periodic work, explicit refresh, resume and teardown (asturksever, #1282).
• Restore minimized test windows before screenshots so native compositor pauses cannot stall browser acceptance (asturksever, #1282).
