+/* ═══ v73：修「切换视图菜单被裁剪」（"点了没反应"的真因）+ 按钮去灰底板 ═══
+   实测证据：
+   ① 祖先链 .navi-view-switch{overflow:hidden} → .navi-dock{overflow:hidden}
+   ② 菜单开/关像素比对有变化（确实渲染），但中心 elementFromPoint 命中 #dashy
+      → 面板超出 52×52 按钮盒的部分被裁剪，既看不见也点不到。
+      （注意：getBoundingClientRect 不受裁剪影响，所以此前我误判它"可见"。）
+   ③ 用户看到的那块"方形灰色背景"= 被裁剪后残留的菜单面板碎片。
+   修法：让承载菜单的 .navi-view-switch / .navi-dock 不裁剪，菜单抬到 z-index 1000。 */
