Accidentally changed typography in theme

[beground]

Hi there,

I accidentally changed the set font in the pagefly preset. I'm not entirely sure how.

Anyhow i want to use Roobert, but I cannot change the typography in the theme to Roobert.

This is how it looks in the pagefly editor

and this is how it looks on the website:

can somebody help me? I unfortunately do not have a backup of the working theme
