 /**
- * V.AI STUDIO - Order Download Fix v1042 FIXED
+ * V.AI STUDIO - Order Download Fix v1047 COMPLETE
  * 
- * FIX OUTPUT: GH Excel/PDF luôn tải được nhiều lần
- * NGĂN NHÂN GỐC:
- * - exportDeliveryExcel/PDF không nhận order parameter
- * - Click nhiều lần gây xung đột download
- * - URL.revokeObjectURL quá sớm
+ * VẤN ĐỀ: Excel/PDF chỉ tải 1 lần, download lần 2+ không hoạt động
+ * 
+ * FIX TRIỆT ĐỐI:
+ * - Monkey-patch URL.revokeObjectURL HOÀN TOÀN
+ * - KHÔNG revoke blob URLs - để download hoàn thành
+ * - Cleanup khi unload (pagehide/beforeunload/unload)
+ * - Hỗ trợ mọi trình duyệt, download nhiều lần
