Close button needs an accessible label

[qjac]

The Close button is currently labeled 'x' which does not convey the function of the interactive control. Add link text, aria-label, or aria-labelledby that accurately describes the functionality of the close link.

Expected Results: Screenreader users should hear "Close modal" (or similar language) when the close button is focused.
