CanvasBid Auction Engine
Design a backend for a digital art auction platform. The system supports different auction formats: English (ascending price) and Dutch (descending price). It needs to handle real-time bids, validate them against the current highest bid/reserve price, and notify all participants when a new high bid is placed or the auction ends.
