 - 背景：后续需要移动端 App 和桌面端 App，但现有主站、固定玩法 runtime、小程序壳和未来 AI H5 sandbox 已经以 H5 为主线；如果移动端重写 React Native UI、桌面端重写 Rust/Tauri UI，会形成玩法、登录、支付、分享和运行态的多套实现。
 - 决策：移动端原生壳采用 `Expo + React Native`，桌面端壳采用 `Tauri`。两者都只作为 `native_app` 宿主壳和 HostBridge adapter，不重写现有 React H5 主站，不把固定内置玩法迁到 React Native / Rust UI，也不让 AI 生成 H5 游戏直接访问完整 HostBridge。Expo 壳通过 `react-native-webview` 承接 H5 与 native 通信，Tauri 壳通过受控 command 和 capabilities 承接桌面能力；新增能力必须先进入 HostBridge 契约和测试。

 - 影响范围：`src/services/host-bridge/`、未来 `apps/mobile-shell/`、未来 `apps/desktop-shell/`、移动端支付 / 分享 / 深链 / 推送、桌面端系统能力、AI H5 sandbox 的 GameBridge 边界。
 - 验证方式：普通浏览器、小程序、Expo 壳、Tauri 壳都能返回正确 `getHostRuntime()`；未支持能力能回退 H5；固定玩法在各宿主中读取同一作品数据和运行态 snapshot；AI sandbox 无法直接调用 HostBridge；Tauri release 不允许任意远端页面调用桌面命令。
