72-hour auctions

Time-boxed bidding on equipment, stock lots and business assets.

How the 72-hour auction works

1.Any listing can be fixed-price only, or auction-enabled.
2.The first valid offer starts a 72-hour countdown.
3.Only the current highest bid and time remaining are public — bidder identities stay private.
4.The seller sees the full offer thread privately and may accept an offer early.
5.The highest valid bid at close wins. Listings with no offers can be re-posted up to 3 times.

Build status: countdowns, offer screens and auction fields are in place. Server-side bid validation, concurrency locks and automatic close-out are not implemented yet.
