    toast.error(errorMessage);
    return;
  }

  try {
    const success = await login(username, password);
    if (success) {
      toast.success("ورود موفقیت‌آمیز بود!");
      onSuccess?.();

      setError(errorMessage);
      toast.error(errorMessage);
    }

  .branding-section {
    display: none;
  }
}

/* Desktop: Split screen layout */
@media (min-width: 1024px) {
  .login-form {
    flex: 1;
  }

    width: 40%; /* 2/5 of screen */
  }
}
```
