With the Kagi Dark and Old School Dark themes, the info tooltip for Quick Answer has link text ("Learn more about use of AI in Kagi") that is almost the same color as the background.
In light mode it is readable but still doesn't look match the rest of the page.
I got the same result on different browsers and on both desktop and mobile.
Colors should be adjusted so the link text is easier to read. Maybe the overall colors for the tooltip could be adjusted to match the site info one.
