 * econ.xmu.edu.cn 移动端适配补丁
 * 用途：覆盖原站点的固定宽度布局，使其在移动设备上可正常浏览
 * 使用方式：
 *   方案A（浏览器油猴/Stylish 注入）：
 *     将此文件 URL 填入 Stylus/Stylish 扩展的 @import 规则
 *   方案B（开发者控制台临时注入）：
 *     复制全部内容，在目标页面 F12 控制台粘贴执行
 *   方案C（Bookmarklet）：
 *     创建书签，URL 填入：
 *     javascript:(function(){var s=document.createElement('style');s.id='econ-mobile-fix';s.textContent=`[粘贴下方全部CSS内容，去掉最外层注释]`;document.head.appendChild(s);})();
