// 浏览器端冒烟：在真实无头 Edge 里验证
//   ① 分发能正常渲染（spine canvas 出现、无异常）
//   ② WE 模拟器确实生效（window.__weSim、面板、替身横幅）
//   ③ 属性下发链路真的打通（经模拟器改 preset → 背景与骨架跟着换）
//   ④ ?propsAt=dom 这条"load 之前下发"的竞态路径不会把配置丢掉
//   ⑤ 单档分发（属性表里没有 preset/bgm）不白屏
//
// 判定只用页面**真实可观察**的量：canvas 是否出现、body 背景、播放器 config。
// 不要用 window.__player —— 那是 tools/serve.mjs 的对拍驱动注入的探针，不是产品行为。
//
// 用法：node tools/checks/smoke-sim.mts [base]
// 前提：调试服在跑（node tools/dev.ts --no-build）。
// 不需要 `--with-sim`：模拟器由调试服自己从 build/scripts/wallpaper-engine.js 提供
// （它默认不进发布产物，见 ADR 0006 §1 与 dev.ts 的路由说明）。
