change link styling to be more visible / underline on hover? about usrse.github.io

I am looking at this some more since I am still noticing that links are hard to find (for me at least, could be my partial color-blindness).

I found these accessibility guidelines discussing how body text relates to links:
https://webaim.org/resources/linkcontrastchecker/

For usability and accessibility, links should be underlined by default. Otherwise, link text must have at least 3:1 contrast with surrounding body text, and must present a non-color indicator (typically underline) on mouse hover and keyboard focus.

We already present underline on hover
(I think here?)

}@media (max-width: 63.9375em) {

But I think it is not the case that our link and surrounding text have 3:1 contrast

I used this tool that suggested using #f18dc7 for links instead to contrast with our text color
https://www.learnui.design/tools/accessible-color-generator.html

If I try that color pairing with the previous tool, it does increase the contrast (I can actually read the text on the page!)
