/* =========================================================
 * BEACON · 国内电商平台 Tabs（设计文档规范化 · 双模深度优化）
 * ---------------------------------------------------------
 * 本文件自包含全部皮肤。beacon-tokens.css 中旧插件皮肤已移除，
 * 不再存在“同特异性后加载覆盖”的隐患（此前暗色分隔线被旧规则
 * 改成 dashed + rgba 浅白，就是该隐患的直接表现）。
 *
 * 设计依据（design-doc-full.md）：
 *  - 分段控件 toggle-pill-group：轨道 = canvas-soft，未选 pill = canvas，
 *    选中 pill = 主色；轨道 padding xs、圆角 4px。
 *  - 徽标：hairline 底 + 1px hairline 描边 + 4px 圆角；
 *    暗面 hairline-on-dark = #26263a（同时也是暗底徽标底色）。
 *  - 卡片：1px hairline + 4px 圆角 + 无投影；层级靠留白与分隔线，
 *    不叠投影、不叠灰底。
 *  - 文字：标题与正文 ink（#000 / #fff）；次级与 mono 眉题 body（#999）。
