+### 默认值迁移
+
+介绍页曾在 v0.6.33 短暂作为默认值。当前版本通过 `welcomePageModeDefaultVersion` 标记把默认值迁回工作区概览：没有该标记的历史设置（包括 v0.6.33 期间被整体快照写入的 `intro`）在启动时一次性重置为工作区概览并落盘；标记为当前版本后，用户显式选择的介绍页会跨重启保留。
 
 ## 实现与边界
 
-`App.vue` 在设置加载完成前保持介绍模式；介绍模式下首页统计、快速连接和 SQL 历史计算直接返回零值或空列表，不读取或排序这些个人数据。`WelcomeScreen.vue` 默认使用介绍模式，个人数据 props 可省略，介绍分支与工作区分支分别渲染。介绍页的按钮布局也不依赖是否已连接数据库。

 该选项只控制**中央空白首页**，不隐藏连接侧栏、已打开的标签、工具栏或用户主动打开的历史窗口，也不删除连接与历史数据。展示或录屏前如需隐藏整个工作区的个人信息，仍需检查这些区域；这项设置不是全局隐私模式。

+1. 无配置、旧配置和无效值均显示工作区概览；保存介绍页模式后重启恢复该选择；v0.6.33 存量的 `intro`（无版本标记）首次启动被迁回工作区概览并持久化。

 3. 切换到工作区概览恢复原有统计与操作，设置取消不保存，应用后立即生效。
