/* XN-kh lượt 1 (21/10/2026) — Xác nhận bản cuối hợp đồng trước khi trình Ban TGĐ (js/ui-xnbc.js). Bám mockup DUYỆT 20/10/2026
   (20261020_App_Mockup-xac-nhan-ban-cuoi.html): thẻ trắng viền nhẹ, chip kết quả có chữ + ký hiệu (không chỉ màu), nền sáng ở cả ba theme.
   Mọi lớp tiền tố hdxn- (không dùng xn- — đã có ở app.css / ui-xemnhanh.js). Màu trạng thái khai bằng mã hex; theme luxe chỉnh tông vàng.
   Khổ hẹp (điện thoại 390 px): một cột, bảng thành thẻ, vùng bấm 44 px. Nạp sau app.css. */
