/* ── 「设为头像」目标选择面板 ──────────────────────────────────────────
 * 这个面板是从 .mi-album-sheet（照片操作面板，z-index 40）里点出来的。
 *
 * z-index 给 60 而不是 50：必须**明确高于** .mi-album-grp-panel(50)。
 * 若恰好同层，谁在上就取决于 DOM 插入顺序 —— 太脆，改一处顺序就翻车。
 *
 * 定位：从屏幕底部起浮（bottom:0），但**不能整屏高**。
 * 首版踩过两个坑，都是实测截图才发现的：
 *   1. 放在 bottom:92px 居中浮着 → 正好盖住照片预览和「保存到相册」那排按钮；
 *   2. 改成 bottom:0 但给了 62% 上限 → 5 个角色就长到 369px，
 *      照样把操作按钮压在下面，用户设完想接着保存得先手动关面板。
 * 现在压到 46% + 行高收紧：常见 3~5 个角色能在不遮挡预览的范围内显示完，
 * 角色多时面板内部滚动（只留一层滚动条，避免嵌套滚动手感变差）。

   设计取舍：
   · 走的是**底部浮层**而不是内联展开。设置面板本身已经很长，
     内联再插一个网格会把「生成图片」按钮推到很远；
     浮层即用即走，不改变原面板的滚动长度。
   · z-index 给到 **600**。
     一开始写的是 90，理由是「要盖住设置面板（面板里有 z-index 60 的
     相册头像面板先例）」—— 这个推理漏了最要紧的一层：
     浮层挂在 document.body 上，而 .karin-chat-app 本身是
     position:fixed; inset:0; **z-index:500**。
     于是 90 被整个 App 容器盖住，肉眼完全看不见 ——
     而 DOM 层面它是正常的（hidden=false、is-open、rect 占满屏），
     纯逻辑断言全部通过，**只有截图能发现**。
     600 > 500 才能浮在 App 之上；同时远低于全局对话框（12000）
     与 toast（120000），不会被自己的提示语压住。 */
