+# `public/` 静态资源目录
+
+[Vite 约定](https://cn.vitejs.dev/guide/assets.html#the-public-directory)：此目录下的文件会**原样**复制到构建后的站点根目录（`dist/`），访问路径为 **`/<文件名>`**。
+
+## 当前文件
+
+| 文件 | 用途 |
+|------|------|
+| `logo.png` | **标签页图标**（`index.html` 的 `rel="icon"` / `apple-touch-icon`）+ **首页与宣传册导航**（`Home.vue`、`BrochurePage.vue`） |
+
+更新品牌时替换本目录下的 `logo.png` 后重新构建即可（可与 `promotion/logo.png` 保持同图或分别维护）。
+
+**注意**：`public` 里的路径不要用 `src/assets` 那种写法；引用时始终用**根路径**，例如 `/logo.png`。
