+升级到 Calcit **0.42.1** 后，请重新安装依赖、生成 JS 并刷新页面。原存档可以继续打开，
 Run、文本输入、复制、错误 HUD 和开发模式的 Reel 面板沿用原有行为。
 
 Reel 使用 `State<Op, Store>`，按钮和文本框通过 Respo 的类型化事件派发具名 `Op`。应用派发使用 `Op | reel.typed/Control`，旧面板事件只在渲染入口解码。按钮路径使用 `CoordKey` union，局部状态使用 `Map Tag Bool`。
 复制边界以 `CopyScalar` 表示 String、Number、Bool、Tag、Symbol，空值仍复制为空字符串，
 复合数据仍会报错。新输出操作只接收 `String`，包括 Run 的格式化结果和输出文本框输入。`Store.data` 保留对任意旧存档数据的支持，恢复成功后才启用自动保存。
