+"""生成 M9 覆盖层 12 个页面壳 wwwroot/pbl_overlay/<key>.ui（bricks 纯 JSON）。
+
+为什么需要：wwwroot/overlay/pbl_overlay_core.js 的 PAGES 注册表 route 指向
+`/pbl_overlay/<key>.ui`，play.js 的 pageUrl() 会拼成
+`/pbl_scense_ext/pbl_overlay/<key>.ui`；页面壳文件不存在则导航即 404（QC #3）。
+
+页面壳职责（只做壳，不做业务渲染）：
+1. 打 `data-pbl-page="<key>"` + `data-pbl-overlay-root="1"` 标记 —— play.js
+   hostPageKey() 据此识别当前页、boot() 据此挂载覆盖层根节点；
+2. 提供 `script` actiontype 按钮调用 `PblOverlayLoader.start({page:...})`，
+   由 loader 按需注入 core/transport/play JS 与 CSS（不在 .ui 里硬写 <script>/<link>，
+   遵守 module-development-spec「ahserver auto-serves .css/.js」）；
+3. 提供返回首页的 `url` actiontype 导航。
+
+route 与 RBAC：新增/删除页面壳必须同步 scripts/load_path.py 的 OVERLAY_PAGES。
