Trying to redo the way I build my site so that it's simpler to maintain, and one
thing that was getting in my way was that ‘lessc’ isn't packaged for Guix. Sass
on the other hand is, so I've switched.
This adds a fer extra colors that work well in dark mode, light should still be
fixed.
Also fixes up a few other visual elements:
- Line numbers should line up with lines of code again.
- The buttons to switch to a different branch at the top of a repository page
looks a little more in-place. It has the same padding as the other form
elements, and the same background as the rest of the header.
- Give other form elements on repository pages more consistent padding.
- Separate the ‘log’, ‘stats’, and ‘plain’ buttons on the repository tree page
so they don't just look like they're one word together.
