   - A private comma connect route still requires tools/lib/auth.py before replay can download it.
   - 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.
-  - --mici-widget-demo makes the small C4 sidebar cycle through widget states for visual review.
+  - --cem publishes fake CEM statuses for desktop visual review in the raylib UIs.
