/* ==========================================================================
   设置页表单栅格
   --------------------------------------------------------------------------
   背景：模板里用了 Bootstrap 风格的 .row + .col-md-*（settings.html 19 处、
   audit_logs.html 5 处），但项目从未引入 Bootstrap，这两个类在桌面端没有任何
   定义 —— .col-md-* 只是普通块级 div，于是「每个字段各占一整行」。
   ≤768px 由 mobile-compact.css 补上了两列，桌面端一直空着，
   结果「系统设置」表单被拉到 800px 高、右侧大片留白。

   这里给设置页的三处表单区补两列栅格。沿用模板已有的 .row / .col-md-*
   做容器，避免再引入一套命名；.settings-span-2 用于必须独占整行的格子。

   不放进媒体查询：桌面端只有这份规则生效；≤768px 时 mobile-compact.css
   也把这几个 .row 变成同样的两列，两边结论一致，手机上不会打架。
