/* OT60 首屏"合并子集"字体（每字重一个文件，~60KB），preload 后首屏文字一次性换上正体，
   不再逐片拉取 unicode-range 子集（首屏文案命中16片/字重）。
   生成：tools/ot60-landing-font.py（fonttools：把 ibm-plex-sans-sc.css 里命中首屏文案的
   分片合并 → 按首屏字符集子集化，脚本内置首屏文案并会重写本文件）。首屏文案变更后
   重新运行该脚本即可（woff2 与 unicode-range 一并更新）。
   必须在 ibm-plex-sans-sc.css 之后加载：字符重叠时后声明的 face 生效，保证首屏只拉本文件。 */
