- Auth flow now waits for user's Enter before starting - Start auth only when user presses Enter on DeviceAuth popup - Proper error handling: missing GOOGLE_CLIENT_ID shows clear message - Error messages displayed in popup with Retry option - Popup shows instructions before auth, URL+code during auth - Handle both verification_url and verification_uri field names from Google - Check HTTP status code and show error_description on failures - AuthError propagated to render function for display - Popup border turns green when URL+code are ready
