CSS concerns for the Wiki

This came up in updating some documents for the wiki and my not feeling great about the likelihood of people coming to them and having a good experience.

I think we could do some reasonably small CSS changes for the wiki that could make it much more inviting and comfortable to read. I’m not sure if it’s the spacing or font-size (probably too large), but it’s just not as readable as the same content here in the forum.

One specific item: I think we should remove the italicization of blockquotes (it looks particularly bad for any paragraph-length or more).
