Feature: Implement a specialized Auction Mode for Live sessions. Unlike standard checkout, this mode introduces a competitive bidding environment where items are sold via a countdown timer. Crucially, a "Buy Now" option remains available to sell remaining stock at retail price simultaneously without ending the auction until inventory is depleted.

Business Benefits

Operational Speed: Shop owners save time by setting one price for 100 items instead of 100 prices.

Urgency & FOMO: The combination of a ticking clock and seeing inventory drop from "Buy Now" users creates a high-pressure environment that accelerates sales.

Higher Margins: Whole-number bidding removes the "cent-skipping" friction, encouraging users to jump by larger increments (e.g., $5 to $10 instead of $5.01).
