   FurryBox — 设计系统
   --------------------------------------------------------------------------
   参考 yunamo.com 的设计语言（不是照抄配色，而是同一套做法）：
     · 深黑实色底 + 实色卡片分层，不用半透明玻璃
     · 1px 极细描边，靠 line 色区分层次
     · 单一强调色（薄荷绿），不用渐变
     · 等宽字体用于域名与数值
     · 圆角分层：10 / 16 / 20

   三个站点（www / id / my）共用。

/* ============================================================================
   按钮反馈 · 全局基础层
   ----------------------------------------------------------------------------
   目的：让**每一个**按钮点下去都有反应，不管它是哪个站点的哪个类。

   之前只有 my 站的 .fbx-btn/.oauth-btn/.dlg-btn 几个类有 :active，
   首页的 search-submit、starry 的 submit/linkbtn 点下去毫无反馈 ——
   用户会觉得"点了没反应"，怀疑是不是卡了。

   设计原则：
     · 按压用 opacity + 1px 下沉，不用 scale —— scale 会让文字重排发虚
     · 只用 :active，不用 JS，零成本
     · 不碰背景色/边框，避免和已有 hover 规则打架
     · 全部走 CSS 变量，各站可覆盖

   放在 design.css（三站共享）而不是各站自己的 css，
   这样新加的按钮天然就有反馈，不用每次记得去补。
