   CHUẨN RESPONSIVE HỆ THỐNG (dùng chung với hero.css)
   ------------------------------------------------------------
   File này áp dụng lại đúng hệ thống 3-breakpoint đã định nghĩa
   ở đầu hero.css. Nhắc lại ngắn gọn:

   1) BREAKPOINT: chỉ dùng 3 mốc — 1023px (tablet) / 767px (mobile)
      / 640px (mobile nhỏ). Mỗi component chỉ 1 block/mốc, không để
      2 block @media cùng mốc rải rác nhiều nơi trong file.

   2) FONT-SIZE mobile: tối thiểu 14px (var(--fs-sm)) cho text nội
      dung/label chính; 13–14px cho label phụ/caption. Không dùng
      12px (var(--fs-xs)) cho text có nghĩa.

   3) TOUCH TARGET: phần tử tương tác (nav arrow, dot, icon-button…)
      tối thiểu 40×40px trên mobile.

   4) KHUNG ẢNH: dùng `aspect-ratio` + `object-fit: cover` thay cho
      `height` cố định.
