Windows SmartScreen Warning
When you first run the app, Windows may show a "Windows protected your PC" warning. This is normal for new apps that aren't code-signed yet — it doesn't mean the app is unsafe.
How to bypass SmartScreen:
- When the blue "Windows protected your PC" dialog appears, click "More info"
- Click "Run anyway" to start the app
- You only need to do this once — Windows remembers your choice
