fawadqureshi007/Insta-king ? reverse-engineered prompt

Build me a small local Flask app that looks like an Instagram login page for security research and demo testing.

I want the page to feel polished and Instagram like, with the login form centered and a static image or styling asset in a static folder. When someone submits the form, capture the entered username and password, along with the time, client IP, browser user agent, and any forwarded IP headers you can see. Print all of that immediately in the terminal in a clear, readable format.

Keep it simple to run from one Python file, with a basic requirements file and easy setup instructions. It should work on localhost by default, and also be easy to switch to listening on all interfaces for LAN testing. If you need to look up current Flask docs online while building it, go ahead.

This is only for an isolated lab environment and dummy credentials, so please make the app obvious and self contained, with no extra services or databases.
