/**
 * T03 真机走查：三键相机契约落在真实 Cesium 上的行为（票 03 / ADR 0008）。
 *
 * 逻辑脚本（t03-camera-contract.mjs）用假引擎把语义测透了，这里只补浏览器里才成立的部分：
 *   · Cesium 默认左键旋转 / 滚轮缩放确实被替换（左键只平移、滚轮只改距离）；
 *   · 三种交互在真机上确实按契约改变相机；
 *   · 未选中时中心就是屏幕中心的地面拾取点（用中心点在画布上的投点位置断言）；
 *   · 选中换中心平滑且保持 heading 与 range，取消选中不回退。
 *
 * 走查用 page.mouse 派发**真实**输入事件（不是合成 DOM 事件），读的是开发态把手
 * `window.__cockpitMap`（见 mapService 的 publishDevHook）与宿主上的 `data-camera`。
 *
 * 运行（需先起 `yarn dev`，服务在 http://localhost:8000/）：
 *   node .scratch/cockpit-shell-panel-layout/verify/t03-camera-walkthrough.mjs
