/* docs.clawcu.ai 左侧导航 + 右侧「本页目录」(SPEC-apps-docs-nav,2026-10-11;参照 DeepSeek API 文档的三栏布局)。
   只在带导航的页面加载(由 scripts/gen-docs-nav.py 写进 <head>),所以这里可以放心改页头等全局样式。
   颜色走页面已有变量:普通文档页是 app.css 的令牌,Jev 页是它自己内联的令牌;变量缺失时用兜底色。
   断点:≥1200 三栏(导航 | 正文 | 目录);921–1199 两栏(目录隐藏);≤920(Jev 原有断点)单栏,导航变成左侧抽屉(☰ 由 docs-nav.js 创建)。 */
