+2. **Package the image**: `npm run ota:package`
+   - This generates a `frontend/bin/www.bin` file.
+   - **Configuration**: If the tool is not in your PATH, add its path to `frontend/.env`:
+     ```env
+     MKLITTLEFS_PATH=C:\path\to\mklittlefs.exe
+     ```

+   - Open the dashboard in your browser.
+   - Go to the **Frontend Update** section.
+   - Select the `www.bin` file and click **Flash**.
+   - The device will automatically write to the inactive partition and reboot.
