/* 版面契约:客服**不是**浮层,它自己占一栏。
 *
 * 旧版把 `.cs-btn` 写成 `position:absolute; top:max(10px,…); right:12px`,
 * 于是它悬在会横滚的 `.tabs` 上面 —— 390px 宽时压住最后一格「超市」22×30px,
 * 320px 时压掉 50×30px 连中心点都被夺走。客人点超市,按到的是客服。
 *
 * 修法是给它真的空间,不是挪偏移量:两栏 grid,第一栏是会滚的 Tab 列,
 * 第二栏是客服,钱包条跨两栏自成一列。
 *   · `minmax(0, 1fr)`(而非 `1fr`)是关键:预设的 `minmax(auto,1fr)` 会让
 *     滚动容器被 max-content 撑开,整页跟着横向溢出。
 *   · 用 `grid-template-areas` 而不是靠 DOM 顺序 —— 这个头部在 repo 里有三份
 *     历史来源已退役;此档只保留 canonical SKU 页面仍在使用的共享样式。
 *     不保证永远一致,按 class 指派位置才三份同时成立。
