Strategy:
  Isolation:
    Edit: DeepClone(source)    # 深拷贝隔离源数据
    Add: CreateEmpty()         # 全新空对象

  Lifecycle:
    Open: v-if=true            # 创建新实例 (推荐)
    Close: Destroy()           # 自动销毁

  ManualReset (Alternative):
    Watch(visible):
      if true: nextTick(resetFields)
    Close: resetFields()

  Cleanup:
    onUnmounted: ClearSideEffects() # 清理定时器/事件/实例
