/* 机场鱼 全站样式
   版面：浅灰蓝的页面底色上放白色卡片；蓝色是品牌色，琥珀色只用来标出名次和提醒。
   字体：标题用自托管的宋体（JCF Display，只含站内标题用到的字），正文用系统黑体。
   机场卡片做成登机牌的样子：左边是名次存根，虚线是撕口。
   写法：手机布局在前，600px、768px、900px、1024px、1200px 几个断点往上加。 */

/* 标题字体：思源宋体 Bold 的子集，只含站内标题用到的字，约 100 KB。
   文件和 ?v= 版本号由 scripts/build-fonts.js 生成（npm run fonts），不要手改这一行。
   字体还没下载完时先用系统字体显示，不会出现空白。 */
