   - form 增加 `quantity: 1`（默认值 1）
   - 模板增加 +/− 步进器 UI
   - 提交数据中加入 `quantity: form.value.quantity > 0 ? form.value.quantity : 1`
+
+## 后端 - 根路由增加版本字段
+
+- `routers/api.go`：
+  - 添加包级变量 `GitVersion`、`GitCommit`、`BuildTime`
+  - `GET /api/` 响应新增 `version`、`gitCommit`、`buildTime` 三个字段
+- `main.go`：`main()` 启动时将变量赋值给 `routers` 包
+- `install.sh` 修复：`BUILD_TIME` 格式改 `YYYYMMDD_HHMMSS`（去空格，避免 ldflags 解析报错）
+
+## Web 前端 - 版本定义 + Footer 显示
+
+- `vite.config.js`：读取 `package.json` 的 `version`，通过 `define: { __APP_VERSION__ }` 注入全局常量
+- `components/AppFooter.vue`：
+  - script 中 `const version = __APP_VERSION__`
+  - 模板中版权行末尾显示 `v{{ version }}`（如 `v0.1.0`）
