/**
 * T37 真机走查：进区锁定与相机区域限位（票 37 验收第 11 条点名的全过程）。
 *
 * 断言的是「进入 → 锁定 → 拉远被夹 → 拖到边界回弹 → 返回 → 闲置回引导」这条链在**真实引擎**上成立：
 *   · 点「进入系统」后 `areaState` 落 locked、顶栏出现「返回全球」、宿主 `data-map-area-state=locked`；
 *   · 区内滚轮真的拉不远（range 被夹在 home.range 12000 内，且**读数与实测一致**）；
 *   · 管线视图切换后仍与现状一致（[400, 6000]，没有被区域收紧得更狠）；
 *   · 拖到边界时中心越出框、松手后弹回框内（`shown.pivot` 最终在框内）；
 *   · 点「返回全球」解除限位并飞到初始全景（heading 0 / pitch −60 / range 2×10⁷）；
 *   · 全球态闲置 10 秒 → 引导层回来；区内闲置**不**回引导页（边界）；
 *   · 全程无页面级报错。
 *
 * 运行（需先起 `yarn dev`）：node .scratch/cockpit-shell-panel-layout/verify/t37-area-limits-walkthrough.mjs
 * 按 AGENTS.md：本脚本不在改代码后自动运行，由维护者明确要求时才跑。
