   updateserver.css — lớp thị giác của trang quản trị Update Server.

   Áp hướng thẩm mỹ đã duyệt ở bản mock: Be Vietnam Pro + JetBrains Mono,
   bo góc 10/6/pill, thang surface nhiều tầng, accent xanh thông, có chế độ tối.

   TÊN CLASS GIỮ NGUYÊN so với bản cũ nên Razor view không phải sửa theo.
   KHÔNG đụng tokens.css: file đó dùng chung với ClinicSolution, đổi --radius*
   ở đó sẽ kéo theo mọi màn bên kia.
