/*
 * 开发文档页面样式（公开页面 /docs，独立于用户中心布局）。
 * 布局：固定顶栏 + 左侧两级目录 + 正文分节阅读 / 展开全部。
 * 企业级极简：白底、1px 边框、0–4px 圆角、阴影不超过 0 1px 2px rgba(0,0,0,.05)、单一品牌蓝 + 中性灰阶；代码块使用浅色背景。
 * 复用 resources/css/app.css 的变量与 .button、.brand-mark、.sr-only、.skip-link，其余类名统一以 docs- 为前缀。
 *
 * 断点：≥1200 桌面；1024–1199 小屏桌面 / iPad 横屏（侧栏收窄）；768–1023 iPad 竖屏（侧栏改为抽屉）；
 *       ≤767 手机（搜索收起为图标、表格按 data-label 卡片化）。
