/**
 * 盲航（space）无头试玩测试 —— 覆盖 docs/design/13-playtest-criteria.md §5（space 关键路径
 * + 边界断言）与 §7（全局通用断言），以及本轮改动（状态 BGM / skipVoice / skip_hint）、
 * §11 round4-live 修复（方向呼喊提前到 spawn / 闪避窗口=呼啸全程 / 护盾 15s+不可用应答 /
 * 保护期断崖过渡 / hit_last 呼喊接力 / feat 教学仅首局），以及 round2 R2 修复
 * （下滑开菜单冷静期防误暂停 / 暂停恢复缓冲 / 回大厅收尾流程 / 警告链呼喊抑制+坠毁掐断）。
 *
 * 用法：tools/node/bin/node web/space/test/playtest.mjs
 *
 * 设计：
 * - 真实加载 engine/{audio,settings,haptics,game}.js 与 vendor/soundtouch.js（纯 JS），
 *   只 mock 浏览器环境：window/document/navigator/localStorage/fetch/AudioContext。
 * - fetch 映射到 web/space/audio/ 真实文件系统：资产缺失 → ok:false（顺带做资产校验）。
 * - decodeAudioData 返回带 duration 的假 buffer（voice 1.0s / bgm 60s / sfx 0.5s）；
 *   ScriptProcessorNode 永不触发 onaudioprocess，voice 自然结束由引擎内部定时器驱动。
 * - 虚拟时钟：setTimeout/clearTimeout/performance.now 全部替换，测试零真实等待。
 * - 手势直接注入 game.onGesture（引擎判定路径之外的稳定注入点，13 号文档允许）；
 *   刷怪方向用 Math.random 队列控制，陨石投放/快进用游戏实例钩子（文档明示允许）。
