/* ══ BA CON SỐ LUÔN NẰM MỘT HÀNG ══
   Bản cũ: flex + `flex-wrap:wrap` + khe 44px + chữ CỐ ĐỊNH 40px. Trên điện thoại, ba ô không
   đủ chỗ nên ô thứ ba RỚT XUỐNG dòng dưới, nằm lệch một mình — trông như lỗi dựng trang chứ
   không như một chủ ý.

   Nay: lưới BA CỘT BẰNG NHAU, không cho xuống dòng. Chữ và khe co giãn theo bề ngang màn hình
   bằng `clamp()` — hẹp thì nhỏ lại chứ không gãy hàng. Đây là cách duy nhất giữ được cả bố cục
   lẫn sự cân đối; ép chữ to cố định rồi bắt ba ô chen nhau thì hoặc rớt hàng, hoặc tràn mép.

   KHÔNG đóng cứng số cột: `dai-ly.html` có NĂM ô chứ không phải ba (day-chuyen và gioi-thieu
   mới là ba). Viết `repeat(3,1fr)` là gãy đúng trang Đại lý — trang quan trọng nhất trong ba.
   `grid-auto-flow:column` để lưới tự đếm: bao nhiêu ô cũng nằm gọn MỘT hàng. */
