- Add stock_status column to products table (in_stock/out_of_stock/unknown) - Detect out-of-stock status on Amazon by checking: - #availability text for "currently unavailable" - #outOfStock element presence - Missing "Add to Cart" button - Add generic stock status detection for other sites - Allow adding out-of-stock products (they just won't have a price) - Update background scheduler to track stock status changes - Display stock status badge in product list and detail pages - Dim out-of-stock products in the dashboard - Show "Currently Unavailable" badge instead of price when out of stock Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
