  final jsonString = extractJSON(text);

  // Parse JSON
  try {
    final jsonData = jsonDecode(jsonString);

    if (jsonData is! Map<String, dynamic>) {
      throw StructuredOutputError.validationFailed(
        'Expected JSON object, got ${jsonData.runtimeType}',
      );
    }

    return fromJson(jsonData);
  } on FormatException catch (e) {
    throw StructuredOutputError.invalidJSON(
        'Invalid JSON format: ${e.message}');
  } catch (e) {
