avipatilpro/CC_Gen — reverse-engineered prompt

Build me a clean browser app for generating fake credit card test data for checkout form testing. It should have a modern responsive design, work nicely on phone and desktop, and make it very clear the cards are fake and only for education or testing, not real purchases.

I want the user to enter a BIN from 4 to 16 digits, then choose how many cards to make from 1 to 100. The app should detect the likely card type automatically, generate numbers that pass the Luhn check, and show the results in a neat list. Add options to include expiry dates, CVV, random names, and a pipe format output so people can copy the results easily.

Also include a fake user details generator that can pull realistic looking user info from an external API and show it in a few useful formats. Keep everything simple, polished, and easy to use with smooth little animations.
