Please address the comments from this code review:
## Overall Comments
- Remove large blocks of commented-out code in WinControl and Browser or extract them behind a feature flag to keep the implementation clear and maintainable.
- Annotate or add a TODO explaining why WinControl now only renders a fixed-width <div> so future readers understand the placeholder intent.
- Consider syncing the hardcoded titleBarOverlay.height (30) with your existing TITLE_BAR_HEIGHT constant to avoid mismatched layouts on Windows.

<issue_to_address>
Returning a static width div may impact layout and accessibility.

If this is a temporary placeholder, add a clear TODO or use a more descriptive placeholder to prevent confusion for users and maintainers.

Commenting out the entire styling logic may lead to inconsistent UI.

If this change is temporary, confirm that the component and application still function correctly without these styles.

<issue_to_address>
Removing the transparent background color may affect window appearance.

Please verify that removing backgroundColor does not result in an unintended opaque window or loss of transparency.

</code_context>

<issue_to_address>
Catching errors when applying visual effects increases stability.

Consider if errors should be communicated to the user or if a retry mechanism is appropriate, rather than only logging them.

Suggested implementation:

```typescript
      const applyEffects = (retry = false) => {
        try {
          // Apply background material
          this._browserWindow.setBackgroundMaterial('mica');
          logger.debug(
            `[${this.identifier}] Visual effects applied successfully (dark mode: ${isDarkMode})`,
          );
        } catch (error) {
          logger.error(`[${this.identifier}] Failed to apply visual effects${retry ? ' (retry)' : ''}:`, error);
          if (!retry) {
            // Retry once after a short delay
            setTimeout(() => applyEffects(true), 500);
          } else {
            // Notify user after retry fails
            if (typeof showErrorNotification === 'function') {
              showErrorNotification('Failed to apply visual effects to the window. Some UI features may not display as intended.');
            }
          }
        }
      };
      applyEffects();

```

- This code assumes a `showErrorNotification` function is available in scope to notify the user. If your app uses a different notification system, replace `showErrorNotification` with the appropriate function.
- If you want to customize the retry logic (e.g., more retries, different delay), adjust the `applyEffects` function accordingly.
