Inventory Deduction Details: The system creates a unique key for each line item combining productId, variant details, and stockItemId. Items can be skipped from deduction if flagged. Shopify variant IDs (prefixed with "shopify-") are handled specially - if no local inventory exists, deduction is skipped but order is still created.
