  状态机接口、MainActivity 全屏封面 + TalkBack
- 《声命线》storyline:末世互动广播剧,3 幕 8 抉择点 4 结局
- 《声东击西》reflex:听声辨位反应,12 波战斗 + BGM 三档 BPM 变速
- 《暗室》escape:3x3 网格密室逃脱,钥匙→铁柜→保险丝→电箱→大门谜题链
- 文档:setup(从零搭建)/ architecture(架构)/ engine-api(引擎 API)/
  asset-pipeline(资产流水线)/ games/*(三款游戏设计文档)
- 资产管线:Qwen3-TTS 对白 + 程序合成音效/BGM + Mureka BGM 的 gen 脚本与台账,
  全部 ogg 资产入库可复现
