/* QFE — Thẻ tải xuống (filecard), mẫu A (QFE 1.51.0).
   Hàng chính: icon loại tệp · tên + "ZIP · 156 KB · 8 tệp font" · nút OneDrive · nút Tải xuống (cả hai dạng viền).
   Dải dưới (.qfe-file-foot): SHA-256 + nút sao chép (assets/front-file.js) bên trái · cụm Cập nhật + nguồn tải (.qfe-file-foot-r) bên phải.
   Nhiều thẻ liền nhau → một danh sách: ẩn dải dưới, hiện ngày ở dòng phụ, nút OneDrive chỉ còn icon.
   Markup: includes/file.php (qfe_filecard_html / qfe_filecard_od_html); thẻ đã lưu được dựng lại khi hiển thị.
   Design language msedu: phẳng, viền 1px, bo 8px (chip 6px), không pill, không shadow; hover đổi viền/màu.
   Nổi khỏi nền trang bằng tương phản phẳng (1.52.3): nền thẻ xám rất nhạt, viền ngoài đậm hơn, dải dưới xám hơn một bậc. */
