- Refactored themes to always load with just a single file. This avoids
a round trip on each request.
- Locally load "Fira Code" when available on the system, then try to
load the woff2 file, then fall back to regular woff.
- Update markup to use relative urls where it is safe. RSS feeds still
use absolute URLs.
- Only set og:image:(height/width) when using the standard color icon.
- Fixed styles on the pagination buttons.
