- adjust main font size
- adjust margins and border radii
- drop borders from keys
- put more items in common.css
- update dark and light style definitions
- use mixing of fg color wherever possible
Dedicated styling is now possible for themes which have a corresponding style-theme.css file. Adwaita:dark gets one, whereas other themes use the new generic fallback theme.
