## Description

When comparing several products, there's no built-in way to see which shops stock all of them. Multi-Product Comparator lets you add products to a compare list and highlights shops that carry every added item — directly on the offer list.

How it works:
1. Visit a product page on a supported site
2. Click "Add to Compare" (floating panel, bottom-right)
3. Open another product page — shops carrying all your added products are highlighted in green
4. Manage the list on the page or via the toolbar popup
