Note: (Partially) automated testing should be possible. This violation can be automatically detected by querying all nav elements (and components) and programmatically retrieving their current width and height to verify they are responsive (i.e., they don't use fixed values). However, a human tester or AI may be required to visually confirm that the element truly adjusts to size changes and does not introduce horizontal scrolling.
