/* 字体别名（提速改造）：
 * 原先 7 个 @font-face 直接指向本站 TTF（每个 10MB+，合计 64MB），
 * 而 a.css / app_a.css / case.css 等共有 96 处 font-family 声明这些家族名，
 * Windows 用户本机没有苹方，浏览器会真的去下载 10MB 级字体文件拖慢首屏。
 * 现改为只做本地匹配（local），零网络请求：macOS 命中苹方，Windows 落到微软雅黑。
 * 需要恢复内嵌字体时，把下面注释里的 TTF 版规则贴回来即可。
 *
 * @font-face{font-family:"PingFangSC-Regular";src:url("PingFang SC Regular.ttf");font-weight:normal;}
 * @font-face{font-family:"PingFang SC-Bold";src:url("PINGFANG BOLD.TTF");font-weight:normal;}
 * @font-face{font-family:"PINGFANG EXTRALIGHT";src:url("PINGFANG EXTRALIGHT.TTF");font-weight:normal;}
 * @font-face{font-family:"PingFang SC-Heavy";src:url("PINGFANG HEAVY.TTF");font-weight:normal;}
 * @font-face{font-family:"PINGFANG LIGHT";src:url("PINGFANG LIGHT.TTF");font-weight:normal;}
