<mark> styling

On the search page, results are styled yellow highlight when they are matched.

This colour doesn't meet colour contrast requirements (against the background)

Non-text content should be 3:1 contrast but it is only 1.03:1 (#ffff00 / #f4f3f3 ) https://www.w3.org/WAI/WCAG21/Understanding/non-text-contrast.html

Its possible that the criteria doesn't apply because it isn't a User Interface Component . However it does give information which isn't available to a particular set of users (low vision).

Not urgent, but interesting...
