Implementation

@override
Future<void> download(
  String url,
  String targetPath, {
  String? token,
  CancelToken? cancelToken,
}) async {
  // Check cancellation before starting
  cancelToken?.throwIfCancelled();

  // On web, just register the URL - no actual download
  // MediaPipe will fetch it when creating a session
  _fileSystem.registerUrl(targetPath, url);

  debugPrint('WebDownloadService: Registered URL for $targetPath');

  // Note: Token is stored but not used here
  // It would need to be passed to MediaPipe when creating session
  if (token != null) {
    debugPrint('WebDownloadService: Token provided (will be used by MediaPipe)');
  }
