-Enable logging to see event flow and diagnose synchronization issues:
-
-```bash
-chromium --bot-mirror-controller-endpoint=127.0.0.1:9990 \
-  --enable-logging --v=1 --log-file="mirror.log"
-```
-
-Check the log file for:
-- Controller startup confirmation on the specified port
-- Client connection messages
-- Event capture and broadcast records
-- Window selection and coordinate transformation details
