/* GeekxyPro兑换站（原强兑换站）前台样式。
   一份独立的样式表：不再叠在权威站的 styles / workspace 之上，也不再有层层覆盖。
   设计参照苹果《人机界面准则》：清晰（文字和留白优先）、让位于内容（少装饰，一个强调色）、层次（毛玻璃导航、柔和的表面）。

   字体：只用系统界面字体（苹方 / SF / 微软雅黑 UI / 思源黑体），不加载外部字体。
   字号：12 / 13 / 15 / 17 / 21 / 28 / 36 px 七级，页面上不出现这七级以外的字号，也没有小于 12px 的字。
   字重：只用 400 和 600。中文字体大多只有常规与粗体两档，其余字重会被浏览器伪造或四舍五入，同一页上看起来忽粗忽细。
   间距：4 的倍数（4 / 8 / 12 / 16 / 24 / 32 / 48）。
   颜色：浅色与深色各一套，只有一个强调色（蓝）；绿、橙、红只表示成功、注意、失败。 */
