This PR introduces responsive breakpoint tests for utility functions, which is a great step towards ensuring our application behaves consistently across different screen sizes. It aligns well with previous decisions to enhance test coverage for responsive layouts and timezone handling. Thank you for your contribution, and I look forward to your updates on the checklist items! 😊

Excellent work on the responsive breakpoint tests for the \�uildQueryParams\ utility function. Simulating viewport changes by mocking \window.innerWidth\ and \window.innerHeight\ alongside dispatching resize events is a very effective strategy. Proving that the URL parameters remain stable and don't leak horizontal layout dependencies onto smaller viewports is exactly what we needed.
