   行健 XINGJIAN · 全站经典组件层（Legacy Components）
   ---------------------------------------------------------------------
   戳：v20260924f

   身份说明：
   本文件原名「style.css · 全站样式主文件」，2026-08-15 版本定义 108 个
   组件类，是全站登录后页面（患者端/医生端/管理端/好物/通知/家庭圈…）
   的样式根。2026-08-24 它被一次「防折行护栏」改动**整体覆盖**为 1303B，
   导致 44 个页面 301 个类名同时失去定义 —— 全站组件样式裸奔。
   本次按归档底本（_archive/2026-08-15-roadshow-bizplan/public/css/style.css）
   恢复，并做两项升级：
     1. 取值全部令牌化 var(--xj-*, fallback)，跟随 xingjian-tokens.css 唯一真源；
        颜色全面对齐现行 VI（主绿 #0e9f6e），废止旧墨绿 #2E7D5B / 纯红 #D32F2F。
     2. 适老化：底本 11 处 0.72–0.8rem（11.5–12.8px）字号全部提到 13–14px，
        满足「界面文字禁止 <13px」铁律。

   边界：本层只负责「旧类名兼容」（.card/.btn/.site-header …）。
   新页面请优先使用 xj-components.css 的 .xj-* 体系。
   文件尾部保留原「防折行护栏」（.topbar 相关），一字未改。

   所有引用均写成 var(--xj-xxx, fallback)，令牌加载失败样式不崩。
