perplexity: low contrast on some pills in all but Latte.

### Is there an existing issue outlining your problem?

- [x] I am using the latest version of the provided userstyle.

### What userstyles are you seeing the problem on?

lbl:perplexity

### Describe your problem.

When I browse perplexities "Discover", there is a suggestion box to the right, where the suggestions do have no to little contrast.

I was able to make this readable by choosing Gray or Red as highlight color, the remaining highlight colors make the text absolutely unreadable.

This screenshot is Mocha with Gray highlight comparing it to Mocha with Rosewater.

### Any additional comments?

_No response_

Reproduce the issue on Perplexity's Discover page using the Mocha theme and different highlight colors, then locate the lbl:perplexity userstyle rules for the suggestion box and its pills. Done means the pill text has readable contrast for every highlight color, not only Gray or Red.
