/* 【已撤销，2026-10-15】这里曾经有一条 'Noto Serif SC'（Bold，GB2312 一级字子集，
   1.10 MB），给 `--serif` 的中文标题用 —— 因为安卓没有中文衬线族名，泛型 serif 回退得又细
   又不搭。用户看过之后不要：不喜欢那个字，也不想为标题多背 1 MB，认为系统字体就很好。
   于是 `--serif` 连同这份字体一起撤掉，页标题改用系统字体（见 tokens.css 的字体族一节）。
   字体文件已删。若以后还想做，做法是：取 noto-cjk 的 Serif/SubsetOTF/SC/NotoSerifSC-Bold.otf，
   用字符表（ASCII + GB2312 符号区 + 一级汉字 3755）过 pyftsubset --flavor=woff2。 */
