   viền, chỉ khác chữ — mắt phải ĐỌC mới biết bấm cái nào, và nút Xóa nguy
   hiểm lại nằm ngang hàng với Chi tiết vô hại.

   Cách phân cấp ở đây:
   - Deploy (primary): nền đặc, nổi nhất, đây là hành động chính.
   - Update / Chi tiết / Xóa: chỉ tô MÀU CHỮ + VIỀN NHẠT, không nền đặc —
     đủ để phân biệt mà không tranh chú ý với Deploy.
   - Copy SSH / Chuyển VPS / Sửa: trung tính, dùng ít nhất.
