Spot: Multi Store Sync

Duplicate product listings with the same SKU are common for unisex products, men's and women's pages. Shopify still deducts stock from only the purchased variant. Spot solves that same-SKU syncing problem without turning every location into one pool. It reads the live inventory change across multi stores, finds matching listings in the same location group, and syncs the delta only there, so retail, warehouse, and online stock stay independent and aligned by location too.
