/* ZenPn — trang tải ứng dụng /download (public/zenpn/download.js). Màu lấy từ biến theme ở :root
 * nên dùng được cả trang khách lẫn trang thành viên. Mỗi nền tảng là một card rời của cùng một danh sách:
 * skeleton nằm chồng lên dòng trạng thái, có dữ liệu thì mờ đi; thân card (nút tải + các bước cài) mở và
 * thu đều chạy; card của hệ điều hành đang dùng nổi lên. Lề trong hàng lấy từ --zc-download-pad, thân card thụt bằng
 * --zc-download-indent cho thẳng tên nền tảng; đặt lề bằng padding vì .zc-download p { margin: 0 } đè margin. */
