Add fit info to homepage

I wasn't sure how to fill the space for items that are fully modeled, then realized some basic at-a-glance "who does this fit" would help!

The load time isn't great, I think I need to break out that dependent subquery, but maybe the stale-while-revalidate will cover it well enough at first.
