Shubh2-0/Shopzilla-Online-Shopping-Platform ? reverse-engineered prompt

Build me a complete Shopzilla style online shopping app where admins, buyers, and sellers each have their own login and can do the things described in the README.

I want buyers to browse products, buy items, return eligible purchases within 30 days, request refunds, add money to their wallet, and see and sort their transaction history. Sellers should be able to add and edit products, manage stock, handle pending refund amounts, withdraw income, close and reopen accounts, and update their profile. Admins should be able to monitor all transactions, filter and sort them by things like ID, date, amount, and GST, view active buyers and sellers, spot out of stock products, and inspect a seller’s listed items.

Make it feel like a real working marketplace with secure role based access, clean forms, and a solid database backed setup. Use the existing project structure if that helps, and look up any current docs online if you need to.
