Comment:
**logic:** The `redirectTimer` is never cleaned up if the redirect succeeds and the page unloads. If the deep link works, the timer will still fire 5 seconds later (potentially in the background), calling state setters on an unmounted component.

```suggestion
      // Set a timeout to detect if the redirect failed
      // If the user is still on this page after 5 seconds, show error
      const redirectTimer = setTimeout(() => {
        if (document.visibilityState === 'visible') {
          setRedirectFailed(true);
          setIsProcessing(false);
        }
      }, 5000);
```

Comment:
**logic:** This condition checks `localStorage` on every render. Since `localStorage.removeItem("redirect-to-native")` is called on line 43, this will be `false` after the first execution, causing the UI to switch from the Tauri success screen back to the web flow screen before the 5-second timer completes.
