NightfallGT/Discord-QR-Scam ? reverse-engineered prompt

Build me a simple Python app that generates a QR code image for a Discord themed demo, but make it harmless and educational only. I want it to create a fresh QR image I can show on screen, with a clean interface and clear steps for running it from the command line or by double clicking a script on Windows.

Please make it easy to install the needed packages, include a way to regenerate the QR image on demand, and add basic instructions in the README so someone new can run it without much setup. If it helps, use the current docs online for the QR code and browser automation parts.

Also add a small note in the app and README that this is only for demonstrations and does not collect accounts, tokens, or any private data. Keep it simple, polished, and working end to end.
