   CoupleBill 指标下钻弹层样式（drill- 前缀 + 规格指定的 .rank-drill-btn）
   移植自 UI 原型稿 drilldown_ui 的 drilldown_proto.css 第 1~12 节（类名词表见原型 README §2），另补方案 B 的 .is-fit；
   R2 返工：<520 横屏不再平移、左侧渐隐盖到标签行、两处文字对比度、删去未使用的首次提示气泡样式。
   依赖 app.css 的变量：--primary --primary-light --bg --text-main --text-sub --border；
   开关复用 payer_and_sharing.css 的 .switch-toggle/.switch-circle，分段复用 app.css 的 .segment-control/.segment-btn。
