async function transactional(operation) {
  const cleanup = [];
  try {
    return await operation(cleanup);
  } catch (error) {
    for (const cleanupFn of cleanup.reverse()) {
      try {
        await cleanupFn();
      } catch (cleanupError) {
        console.error('Cleanup failed:', cleanupError);
      }
    }
    throw error;
  }
}
