   - Use multiple UI flags together if you want more than one desktop UI at once.
   - -nav injects a fake navigation demo stream and blocks replay from publishing navInstruction/navRoute.
   - --cem publishes fake CEM statuses for desktop visual review in the raylib UIs.
+  - -alert blocks replay from publishing selfdriveState and fires a fake critical full-screen red alert (alertSize=full, alertStatus=critical) 20 seconds after the demo publisher starts (10s for replay route + UI to come up, plus 10s for the user to open Settings). Default alert text mimics a real controlsMismatch event; run tools/replay/fake_alert_demo.py directly to override --text1/--text2/--delay.
