 * ThinkBox ID — trang chủ hub (launcher tối giản): nền trắng, logo và ô tìm kiếm dạng viên thuốc ở giữa, hàng biểu tượng ứng dụng tròn bên dưới.
 * Người dùng: người vận hành vừa đăng nhập, cần mở đúng app trong một thao tác; không cần gì khác trên màn hình.
 * Điểm nhấn: ô tìm kiếm; mỗi app có biểu tượng màu riêng (cùng bảng màu với trang đăng nhập); app chưa nối mờ, nét đứt.
