WHY IT NEEDS A POLICY

Why wifi-template needs a policy

This tool creates a QR code artifact encoding WiFi credentials. It writes/generates a new file or data object, and has no destructive or financial effects. Severity is medium because it encodes sensitive network credentials (SSID/password) into a shareable QR code, which could expose network access if misused.
