Hi Jen looks great!! Love the inline reference to the sqlfluff rule code it is so convenient.

I was able to see the changes really clearly by building a local site off of the PR branch. FYI, something I noticed is that the current version of the website looks like this (notice the left sidebar)

And when I build this PR branch locally the website looks like this

So I actually merged main into this PR branch (just locally for me) to see what the site would actually look like with this PR's changes

Doesn't impact this PR but wanted to mention it for others.
