/* UK MASTER ACADEMY · LỚP GIAO DIỆN CHUNG CỦA VIỆN (01/10/2026, Thầy chốt "đồng nhất mọi trang")
   Nạp SAU khối <style> riêng của app.html, lop.html, cam-nhan.html để đè lên giao diện cũ.
   Hai sắc giống trang chủ Viện:
     html[data-mau="ngay"]  giấy kem, mực tím, son đỏ, ngũ hành làm điểm nhấn
     html[data-mau="dem"]   trời đêm tím thẫm, chữ trăng, vàng sao làm điểm nhấn
   Không đổi id, không đổi lớp mà mã JS đang dùng, chỉ đổi cách trình bày.
   Biến --ukma-* vẫn giữ tên cũ nên mọi khối viết sẵn tự ăn theo màu mới. */
