/* ---------- 本地字体子集（Google Fonts 外链已移除，全部走本地） ----------
   由 tools/make-font-subset.py 按项目全部用字子集化生成，家族名与原 Google 字体
   保持一致（'Ma Shan Zheng' / 'Noto Serif SC'），所以下面所有 font-family 声明
   一行都不用改。
   不提供本地 Noto Sans SC —— 它在字体栈里后面就是 system-ui / 苹方 / 微软雅黑，
   各平台系统无衬线字体质量都足够好，没必要多传 200KB。
   若改了文案、出现子集外的字导致回退成宋体，重新跑 make-font-subset.py
   并更新下面的 ?v= 版本号。 */
