/* blog 共享样式：与站内统一 header / footer 对齐。
   站内的 header/footer 由 React 组件在运行时渲染（src/components/SiteHeader.tsx、
   src/components/marketing/SiteFooter.tsx），blog 是纯静态页，故在此复刻其 Tailwind 渲染结果。
   关键取舍：导航链接是静态 <a href>，不依赖 JS 就能被爬虫发现（对 Bing 这类弱 JS 渲染的引擎尤其重要）。 */

/* ---------- 页面基础 ----------
   之前这里没有 body 规则，导致生成的页面：底色只是浏览器默认值（系统深色模式或"自动深色"
   会把它渲染成灰底）、字体退回浏览器默认（桌面上常是衬线体）、body 还留着默认 8px 外边距
   （header/footer 因此不能通栏）。这里显式声明，所有 blog 页共用。 */
