/* ===== 侧边栏：展开 248px / 收起 64px 图标轨（2026-09-22 按主流规范重做）=====
   调研结论（Linear / Vercel / Notion 及主流 admin 模板一致）：
     · 展开宽度 240–300px（窄于此会截断中文标签 → 用户反馈"太窄"）
     · 收起**不是隐藏**，而是 64px 图标轨：图标常驻 + hover 提示（title），
       收起后仍能一眼看到"有哪些模块"，也不会像浮动按钮那样盖住内容
     · 交互：切换控件固定在品牌行；状态存 localStorage；宽度过渡 200ms */
