exchange the unholy Bulma frontend with styled components #23

The rabbit hole project started doing this and somewhere deep in the history I also did that. Decided to go Bulma for brevity but as it turns out... it's really that bad ;)

My suggestion is: https://v2.grommet.io/

this would be a major rewrite but since the frontend is still very basic at the moment, this is the right time to start it.
