/* ── BASE967-42（UI045）：窄栏下底部按钮被助手浮钮遮挡 ─────────────────────
   900×800 实测（证据 967-ui045-narrow-overlap.json/png）：底部「关闭」矩形
   x813/y713/w56/h34，中心命中的是 `.ai-fab` 的 SVG 而不是关闭按钮 —— 点下去
   打开助手、草稿没关。根因：`deepseek.css` 的 `.ai-fab` 是全局
   `position:fixed; right:20px; bottom:20px; z-index:69`，跟本页靠右的 `.dlg-foot`
   抢同一个右下角，**邮件页未为浮钮避让**。

   修法按整改计划原话：「优先**布局避让**或将助手入口纳入不遮挡区域，
   **不能仅提高另一按钮 z-index 互相遮住**」—— 所以这里做**布局避让**：
   窄栏下给 `.dlg-foot` 右侧让出浮钮的占位，把按钮推到浮钮左边。
   **不动 `deepseek.css` 的全局浮钮**（那是所有页共用的入口，改它影响面太大）。
   **也不调 z-index**（调了只是换个按钮被遮）。

   尺寸怎么来的：`.ai-fab` 是 `right:20px` + `padding:0 14px` + svg 15px + gap 7px
   + 文字 ≈ 70px，合计约 122px 宽；再留 18px 间距 → 右侧让 140px。
   窄栏下对话框满宽，`.dlg-foot` 的 `justify-content:flex-end` 就把按钮推到
   视口右缘 —— 这 140px 正好避开浮钮那一段。宽屏下对话框不满宽、浮钮不重叠，
   所以只在窄栏加（media query），不给宽屏平白多出 116px 空隙。

   ★ 2026-10-17 追加：**不只窄栏，宽栏也要避让**。判据加了「几何上不重叠」那条后
   抓出宽栏 1400×900 仍相交（按钮 y864-898 × 浮钮 y842-880）—— 中心只是**刚好差 1px
   没被遮**，点按钮边缘就点到浮钮。所以改成**只在浮钮 `.show` 时避让**（`:has()`）：
   浮钮收起时按钮照常靠右，展开时让位。不给宽屏平白留空隙，也不漏宽栏遮挡。 */
