/* 站点页头与页脚的样式 —— app/templates/partials/site-{header,footer}.html 的那一份。
 *
 * 页面自己的 CSS 管版面，外壳只管这两块，所以几张公开页 include 同一份 partial 时长得一样。
 * 颜色走下面那份 `--h2-*`，引用时仍带回退值：万一哪天页面漏挂这张表也不会裸奔。
 *
 * 与海外那份的差别：
 * - 语言切换在页头用国内的 `.langdd`（海外把它藏起来、改用页脚三语按钮），所以没有
 *   `.topnav~.topr .langdd{display:none}`，也没有 `.status-foot-lang`。
 * - 页脚多 `.bf-lang`（国内两语按钮）、`.bf-mail`、`.icp`（备案号）三组。
 * - `.sr-only` / `.skip-link` 从海外 a11y.css 摘出来放这里：国内不引那张表。

/* 视觉 token 与正文字体栈，五张公开页共用这一份定义 —— 以前 index / pricing / login /
   checkout / gallery 五张 CSS 各抄一遍，值一样只是因为没人改过。外壳这张表排在页面 CSS 之前
   （app/templates/build.py 的 styles 顺序），所以页面要改哪个 token 照旧在自己那张表里重定义。
   页面私有的 token（pricing 的 --h2-body、login 的 --h2-jade/--h2-verm、checkout 的
   --checkout-*）和两张表取值本就不同的 --h2-line 都留在各自页面里。 */
