     8. `TopToolbar.vue` 接入模板信息和保存状态。
     9. 执行前端构建验证。
 - **执行结果**: 完成任务 067-073，基础 MVP 任务清单 001-073 已全部标注完成。

+- **执行原因**: 用户要求提交当前代码后继续推进项目实现。
+- **执行过程**:
+    1. 检查 git 工作区，确认上一轮代码已提交且无未提交变更，因此不创建空提交。
+    2. 新增前端模板 API 模块，封装 `GET /api/templates/{id}` 与 `POST /api/templates/{id}/blocks/{blockId}/config`。
+    3. 改造 `templateStore`，从后端模板详情接口加载模板、预览 HTML、blocks、tree 和 configs。
+    4. 改造配置保存逻辑，保存时调用后端 block config upsert 接口。
+    5. 改造 `TemplateEdit.vue`，从路由参数读取模板 ID 后加载对应模板。
+    6. 执行前端生产构建验证。
+- **执行结果**: 前端模板编辑页已从纯 mock 数据推进到后端接口驱动，构建验证通过。
