/* ==========================================================================
   发卡商城 · 后台管理样式（Apple 风格 v2，2026-09-15）
   设计三原则：Clarity（内容优先）/ Deference（界面退让）/ Depth（层次感）
   - 单一强调色 #0071e3，无渐变、无彩色装饰块
   - 系统字体栈 SF Pro / PingFang SC，字重仅 400 / 500 / 600
   - 卡片 18px 圆角 + 极淡描边 + 柔和投影；胶囊按钮；玻璃质感侧边栏
   - 缓动统一 cubic-bezier(.25,.1,.25,1)；末尾有 reduced-motion 兜底
   - 所有旧类名 / 变量名全部保留，模板与 JS 无需改动即可生效
