   Landing page16 - "Hoàng hôn"
   Cùng bộ với mẫu đăng nhập 6: nền sáng ấm, gradient hoàng hôn cam - hồng - tím,
   mặt trời lặn sau dải đồi, điện thoại nhà sáng tạo nội dung, thẻ viền gradient,
   nút bo tròn. Trang "lặn" dần từ chiều vàng tới chạng vạng ở cuối. Tiền tố class dk-.
   Font: Be Vietnam Pro (có italic để nhấn chữ).
