 /**
- * V.AI STUDIO - Order Download Fix v1045 FINAL
+ * V.AI STUDIO - Order Download Fix v1042 FINAL
  * 
- * VẤN ĐỀ: 
- * - Excel/PDF GH chỉ tải 1 lần, download lần 2+ không hoạt động
- * - Modal chi tiết đơn hàng bấm "GH Excel" không nhận order data
+ * VẤN ĐỀ: Excel/PDF chỉ tải 1 lần, download lần 2+ không hoạt động
  * 
  * NGĂN NHÂN GỐC:
- * - Hàm exportDeliveryExcel/PDF trong qr-payment.js không nhận tham số order
- * - URL.revokeObjectURL được gọi quá sớn
- * - Click nhiều lần gây xung đột
+ * - URL.revokeObjectURL() được gọi quá sớm (5s - 60s)
+ * - Safari/Firefox cần thời gian download lâu hơn
+ * - Blob reference không được giữ
  * 
  * FIX: 
- * - Patch exportDeliveryExcel/PDF để nhận order parameter từ order-store.js
  * - Monkey-patch URL.revokeObjectURL để delay 5 phút
- * - Thêm click protection (chống bấm nhiều lần)
  * - Store blob reference để dùng lại
+ * - Chỉ revoke khi tab unload hoặc timeout
