   霞鹜臻楷 GB（LXGW ZhenKai GB）—— 举例项目的默认中文字体
   ---------------------------------------------------------------------------
   来源：举例项目/Aaalice_NAI_Launcher-Android/fonts/LXGWZhenKaiGB-Regular.ttf
        （pubspec.yaml:110-113 声明的 family = "LXGW ZhenKai GB"，唯一字重 Regular）。
   **已子集化（2026-10，用户要求「做子集」）**：
     · 原 TTF 17,482,814 B（17.5 MB）/ 无损 woff2 9,522,360 B（9.1 MB）
     · 子树集：GB2312 全部 6763 汉字 + 本项目源码/文案里出现的 CJK 字符（44 个生僻字，如画师名/角色名）
       + ASCII 可打印字符 + 常用中文标点 ⇒ 共 6940 个字符
     · 体积：woff2 **2.48 MB**（≈原 woff2 的 27%，省 73% 带宽）；字形 23878 → 6923
     · 覆盖校验：6940 个目标字符中 **6923 命中**，缺失 17 个全是 emoji（原字体本来就没有）
     · 子集字符清单：`public/fonts/_subset_chars.txt`；重建命令：fontTools.subset --text-file=_subset_chars.txt --flavor=woff2
   ⚠ **只声明 woff2**：TTF 已不再作为 src 兜底（17.5 MB 太重，且 woff2 覆盖全部目标浏览器；
     需要兼容极老浏览器时再把它加回来）。原 9.1 MB woff2 备份在 LXGWZhenKaiGB-Regular.woff2.bak（不入库）。
   ⚠ font-display: swap：中文字形未就绪时先用回退字体渲染，绝不阻塞首屏。
   unicode-range 不写：西文也会命中它——所以**不要**把它放到
     --ds-font-sans 的首位（那会让英文/数字失去 Source Sans Pro 的多字重层次），
     而是只作为「中文字体」插在原有西文字体之后（见 tokens.css / generation.css 的字体链）。
   ⚠ 子集化的代价：**子集外**的生僻字（极罕见的姓名/异体字）会回落到系统字体，字形略有差异。
     若线上收到「某字显示成系统字体」的反馈，把该字补进 _subset_chars.txt 重新生成即可。
