/**
* Error Boundary Tests
*
* These tests verify that error boundaries work correctly and handle errors gracefully.
* Tests cover:
* - Error boundary display when errors occur
* - Error recovery (retry functionality)
* - Navigation from error state
* - Error boundary in different contexts (pages, components)
*
* To run error boundary tests:
* - Run: npx playwright test error-boundary
