-// mutation_add_request.go
-//
-// Registers the AddRequest mutation. This mutation is a higher-level intent
-// (add by SKU + quantity) which may translate into either:
-//   - Increasing quantity of an existing line (same SKU), OR
-//   - Creating a new item by performing a product lookup (via getItemData inside CartGrain.AddItem)
-//
-// Behavior:
-//   - Validates non-empty SKU and quantity > 0
-//   - If an item with the SKU already exists: increments its quantity
-//   - Else delegates to CartGrain.AddItem (which itself produces an AddItem mutation)
-//   - Totals recalculated automatically (WithTotals)
-//
-// NOTE:
-//   - This handler purposely avoids duplicating the detailed AddItem logic;
-//     it reuses CartGrain.AddItem which then flows through the AddItem mutation
-//     registry handler.
-//   - Double total recalculation can occur (AddItem has WithTotals too), but
-//     is acceptable for clarity. Optimize later if needed.
-//
-// Potential future improvements:
-//   - Stock validation before increasing quantity
-//   - Reservation logic or concurrency guards around stock updates
-//   - Coupon / pricing rules applied conditionally during add-by-sku

-// 	}
