vijeelakshmi/Online-Auction-System ? reverse-engineered prompt

Build me a full stack online auction app where people can sign up, create auctions, browse active listings, and place bids in real time.

I want the auction pages to update instantly when someone bids, show the current highest bid, remaining time, and whether the auction is open or closed. Sellers should be able to manage their own auctions, add basic details and images, and see the bidding activity. Buyers should be able to track auctions they care about and get live updates without refreshing the page.

Please make it feel clean and easy to use, with a simple home page, auction listing page, auction detail page, and basic account flows. Use a modern JavaScript stack and set it up so the real time bidding works smoothly. If you need to look up current docs online for anything, go ahead.
