+Launches the standalone desktop application window (powered by Tauri & WebView2). No web browser tabs or command windows required.
+
+### 2. Development Mode (Hot Reload)
+```powershell
+# Run Tauri desktop app with live reload:
+pnpm --prefix frontend tauri dev
+
+# Or run frontend and backend independently:
+cd backend && .\.venv\Scripts\python -m uvicorn app.main:app --reload
+cd frontend && pnpm dev
+```
+
+
 ## First-Release Scope
