- productVariantsBulkCreate and productVariantsBulkUpdate now enforce a maximum of 50,000 inventory quantities per mutation to support up to 2048 variants per product
- Exceeding the limit returns a userError (INVENTORY_QUANTITIES_LIMIT_EXCEEDED) with guidance to batch operations or use inventorySetQuantities/bulk mutations
- The change ensures reliable performance when handling large variant sets and complements the new 2048‑variant product limit
