Exit Codes

Code	Meaning	Trigger
0	User requested 30-minute extension	"Keep Working" / "Lavora ancora" clicked
1	Machine shut down	Timeout, "Shut Down Now" / "Spegni ora" clicked, or unhandled error

Behavior

• On launch a dialog appears on top of all windows and cannot be minimized or dismissed via the title bar.
• A 60-second countdown timer with a draining progress bar gives the user a clear visual of remaining time.
• At 30 seconds remaining the UI shifts to red and prompts the user to save their files immediately.
• On timeout or "Shut Down Now" the script executes shutdown.exe /s /t 0 and exits with code 1.
• On "Keep Working" the script exits with code 0 and does nothing — the RMM operator is expected to handle the extension workflow based on the exit code.
