   api-bank/assets/ui.css — HỆ THỐNG GIAO DIỆN DÙNG CHUNG
   ---------------------------------------------------------------------
   Dùng cho: index.php · token.php · quan-ly-bank.php · lib/user-log.php

   PHONG CÁCH: kính mờ (glassmorphism) trên nền aurora chuyển động rất chậm,
   sáng/tối đặt cùng bảng màu, bo góc mềm, chữ Inter + JetBrains Mono.

   CÁCH DÙNG:
     Trang nạp lib/ui.php rồi gọi ab_ui_head() — trang đó KHÔNG cần khai
     báo <link> hay <script> nữa. Mọi class định nghĩa ở đây dùng được
     ngay, kể cả các fragment nạp bằng AJAX.

   QUY ƯỚC:
     - Biến màu mới dùng tiền tố --ink/--mut/--glass...
     - Cuối file có một lớp TÊN CŨ (--tx, --muted, --bg, --panel...)
       trỏ về tên mới, để CSS riêng của từng trang không phải sửa gì.
