/**
 * T41 真机走查：监测点定位与面板锚定接入（票 41）。
 *
 * 逻辑闸门（t41-point-locate-anchor.mjs，37/37 + 变异 15/15）已经把定位档位解析、
 * 竞态作废判据、锚定四向布局、离屏判据与统一入口的接线测透了；这里只补**只有在真机才成立**的部分：
 *   1. 点地图上的监测点 → 相机**真的**飞到该点位（`settled` + hpr = 配置点位档，range≈500）；
 *   2. 详情面板**真的贴着**该标记（面板矩形与标记投影的几何关系），且不压住图标；
 *   3. 面板四向避让：标记贴到画布右/左/下/上边缘时，面板翻到对应侧；
 *   4. 标记完全离开画面 → 面板隐藏 + 顶栏出现暂隐入口（带原因与关闭）；回到视野自动恢复；
 *   5. 关闭详情 → 面板消失而**镜头不回退**（ADR 0008）；
 *   6. 台账卡片与地图点选走**同一入口**（都触发点位级定位）——票 41 改写了票 18 的旧语义；
 *   7. 无地图位置（后端 `renderable=false`）→ 固定详情 + 非空原因，且**不创建锚点**；
 *   8. 全程无页面级报错。
 *
 * 运行（需先起 `yarn dev`；`AGENTS.md` 要求不自动跑构建/调试命令，故由维护者按需执行）：
 *   node .scratch/cockpit-shell-panel-layout/verify/t41-point-locate-anchor-walkthrough.mjs
 *   COCKPIT_BASE=http://localhost:8001 node ...（端口不是 8000 时）
 *
 * 两个沿用票 10 的真机坑（换成"直接点屏幕中心"必然假失败）：
 *   · 相机落位是**阻尼飞行**，必须等 `shownPivot` 贴到目标再点；
 *   · 贴地标记与"高度 0 的中心"之间有地形高程差 —— 先用引擎拾取找到标记真实屏幕坐标再真点。
