Execution

1. Start Development Server

   • Run in background: ${DEV_SERVER_CMD:-pnpm dev}
   • Wait 5 seconds for server startup

2. Verify Server Running

   • Check if port ${DEFAULT_PORT:-5173} is responding
   • If not responding after 10s: Report error

3. Report Status

   • Confirm server is running
   • Display URL: http://localhost:${DEFAULT_PORT:-5173}/

• Use Ctrl+C in terminal to stop server
• Default port: 5173 (Vite default)
