vrushabhakamdi-dev/wifi_qrcode_generator ? reverse-engineered prompt

Build me a simple Python app that creates a QR code for a WiFi network.

I want to be able to set my WiFi name, password, and security type in the script, then run it and have it generate an image file I can share with guests. When someone scans it with their phone, it should connect them to the WiFi without them typing the password manually.

Please make it save the QR code as a PNG automatically, and keep the script easy to understand so I can change the network details myself. If you need to check the latest docs for the QR code library or image saving, feel free to look them up online.

A small command line script is fine, no need for a big interface right now, but it should be clean and work reliably.
