/* Skooch 自适应日程规划助手 —— 样式
   ------------------------------------------------------------------
   视觉风格参照 Taskade（https://www.taskade.com）：
     · 近黑分层深色界面（#050505 / #0a0a0c / #18181b / #1c1e21）
     · 品牌主色为红粉 #ff2d60，辅以紫 #a767e5 / 青 #12bcfe / 绿 #4fcf70 / 黄 #fad648
     · 几何无衬线字体（Geist Sans），中文走系统中文字体
     · 大圆角、极细描边、柔和发光阴影、渐变高光
   工程约束（不得违反）：
     · 核心页面支持 360~1920 像素宽度（USR-0049）
     · 零外部依赖：不引用 CDN、在线字体或外部图片；
       Geist 不可用时回落到 system-ui，观感保持一致
     · 所有原有类名与 CSS 变量名保持不变，JS 无需改动
