   官网样式（首页 / 插件文档 / API 文档共用）
   ===========================================================================
   约定（改之前先读）：
   1. 只允许本文件 + /assets/*.js，页面里不写行内样式以外的第三方资源。
      官网的 CSP 是 `default-src 'self'`，字体、图标、CDN 一律不许引。
   2. 图标全部是内联 SVG 或 CSS 几何图形；产品截图用 CSS 画出来的"示意面板"
      （零请求、不糊、深浅色都不需要另出图）。
   3. 三档断点：≤1080 / ≤860 / ≤560。手机优先保证"按钮能点、字能读"。
