This is followup polish that came in response to pixel pushing session on https://phabricator.wikimedia.org/T265666. For whatever reason these bugs could not be figured out live, so we need to do a followup to address these:
- Navigation bar should have a slight background color on the modal. I was going to try .midBackground but it doesn't seem to respond to any colors I try to give it.
- The Close button in the navigation bar on the modal should be the themed link text color. This also seems unresponsive when I try to set it.
- Side-scrolling cells do not seem to have any corner radius. The ideal to shoot for is the radius and shadow amount from the On This Day side scrolling cells.
- Text in article content slightly shifts when you change themes the first time. This only seems to happen on articles that don't have a header image though, so this one is not a must IMO.
