Notes

•Some operations require Accessibility permission in System Settings > Privacy & Security > Accessibility.
•System Events automation requires user approval on first use.
•Wi-Fi interface name may vary (Wi-Fi, en0). Check with networksetup -listallhardwareports.
•Sleep/restart commands may not work in all contexts.
•Combine with manage-cron for scheduled automation (e.g., toggle dark mode at sunset).
