  Khung ảnh bìa: tỉ lệ CỐ ĐỊNH, ảnh dùng object-fit: CONTAIN.

  Ảnh bìa do biên tập viên tải lên, mỗi lần một tỉ lệ khác nhau. Ba cách xử lý:

  - cover  : lấp kín khung, khung luôn đều, nhưng XÉN mất hai mép. Ảnh bìa ở đây
             là banner có chữ nên xén là mất chữ — không dùng được.
  - height:auto : hiện đủ, không xén, nhưng chiều cao mỗi thẻ một khác, hàng thẻ
             so le theo tỉ lệ ảnh người dùng tải lên.
  - contain: hiện đủ VÀ khung luôn đều. Đổi lại có viền nền ở hai cạnh khi tỉ lệ
             ảnh lệch khung — để nền trùng màu thẻ thì gần như không nhận ra.

  Đã chọn contain: bố cục ổn định bất kể ảnh tải lên to nhỏ ra sao, mà không mất
  nội dung nào của ảnh.
