aman-sw062/file-access ? reverse-engineered prompt

Build me a simple paid file access app.

I want users to be able to sign up, pay for access, and then only open the files they are allowed to see. If their access expires, they should lose access automatically and see a clear message telling them it’s expired and how to renew.

Make it easy for me to add and manage files, set expiry dates, and mark some files as free if needed. I’d also like a basic admin area where I can see users, active subscriptions or access status, and quickly turn access on or off.

Keep the interface very simple and clean, with a login page, a file list, and a page for viewing or downloading an allowed file. Use whatever current docs or libraries make sense, and if anything needs to be checked online, look it up.
