sygnialabs/evilginx3 ? reverse-engineered prompt

Build me a local security awareness demo that simulates a fake login page and shows how reverse proxy style phishing can trick people, but only in a safe lab and without collecting real credentials or bypassing any accounts.

I want it to be a standalone Go app with a simple web interface and basic DNS and HTTP handling so I can run it locally, test against a dummy site, and see how the flow works end to end. It should log harmless test submissions, store sample session data for training purposes, and make it easy to swap in different demo pages. If you need to, look up current Go docs online.
