/**
 * 采集原型 DEMO 的模型工程出厂基线，作为「正式环境要和 DEMO 一致」的唯一基准物。
 *
 * 产物落到 `unreal_tran_web/scripts/fixtures/bridge-erector-demo-baseline.json`，
 * 由 `unreal_tran_web/scripts/emit-model-bridge-erector-seed.mjs` 读取生成数据库种子。
 *
 * 为什么必须从浏览器采集，不能从 profile 推导：
 *   文档里 `model.objects`（187 个部件语义 + 114 条材质）与
 *   `environment.objects`（70 个环境对象布局）是 `captureModelObjects()` /
 *   `captureOutdoorScene()` 从活的 three.js 场景里采下来的，
 *   `equipmentModelProfiles.ts` 只有机构轨道，推不出这两块。
 *   丢了它们，下游 `applyModelEditorOverrides` 就回放不出部件语义与 PBR 质感。
 *
 * 关键点：必须用全新 browser context。
 *   原型启动流程是 loadModel -> restoreAutoSave()（读 dt-editor-project-v2），
 *   有存档就恢复存档、没存档才走 createBaselineProject()。
 *   带着上一次的 localStorage 打开，采到的是那份存档而不是出厂基线。
 *   报告里的 `hadAutosaveBeforeDump` 必须是 false 才算有效采集。
 *
 * 前置：`unreal_tran_web` 的 dev server 或 preview 在 6180 上跑着，
 *       且 `public/legacy-model-editor/` 已由 stage-legacy-model-editor.mjs 生成。
 *
 * 用法（在 ute2e 下）：
 *   node tools/dump-model-demo-baseline.mjs
 *   node tools/dump-model-demo-baseline.mjs   # 自定义地址用 TARGET 环境变量
 *
 * 只覆盖模型制作，不涉及场景制作。
