/* Tông SUN của Sun PhuQuoc Airways. Hai lớp:
   - Lớp ấn tượng (đăng nhập, đầu trang chủ): luôn nền tối, có vòng HUD và chuyển động.
   - Lớp làm việc (mọi màn hình còn lại): ít màu, không chuyển động liên tục; cửa sổ, menu và thanh
     trạng thái mang nét HUD (góc vạch, chữ đơn cách, viền vàng mảnh). */
