/**
 * T45 真实用户路径走查：进入系统 → **真实鼠标点地图标记** → 展开设备点 → 逐台拾取。
 *
 * 为什么另起一个脚本：既有 `t45-overlap-walkthrough.mjs` 用 DEV 把手 `selectMonitoringPoint()`
 * 打开点位（那是"统一入口"，但不是**用户的手**）。维护者人工走查反馈「进入系统→点开监测点→
 * 展开设备点」不成立，所以这一趟必须全程用真实鼠标命中**地图上的标记**：
 *   1. 真实点击监测点标记（坐标由只读 `getPointMarkerTargets()` 投影给出）；
 *   2. 断言点位详情真的打开（不是靠 DEV 入口开的）；
 *   3. 真实 hover / click 聚合符号 → 粘性展开；
 *   4. 真实 click 展开后的设备点 → 选中并进设备级。
 *
 * 场景激活走 **URL 通道** `?scenario=xxx`（人工测试同一条入口；Console 全局变量刷新即丢）。
 *
 * **相机收敛纪律**（本脚本第一版踩到的坑）：相机飞行/收敛期间投影出来的屏幕坐标会漂移
 * （同一标记两次读可以差 80px），拿过期坐标去点必然打不中。所以每次点击前都必须
 * 先等 `getCameraState().settled`，再**当场重读**坐标，然后立刻点。
