How Does Relume Load Google Fonts Like Barlow in Webflow When They Don’t Appear in the Project Settings?

Greetings Relume, I have a question about how Relume loads fonts into the Webflow Designer. I have a Webflow project that I used the Relume Style Guide to build. The fonts are Google Fonts, Merriweather and Barlow, were used in the Style Guide and then I cloned the Style Guide into Webflow. Proceeded to build and launch the website, however, the Merriweather and Barlow fonts are not showing in the Settings > Fonts section of the Webflow project, nor are they uploaded as custom fonts. Both of these fonts render just fine on the published website (and staging too) but when I view the Relume generated Typography variables for Headings and Body, one of the fonts, Barlow, appears as the selected Body font, but when I click on the dropdown to change it, it doesn’t appear in the list. Merriweather is in the list because I think it happens to be one of the Google Fonts that’s preloaded into every Webflow project. I’m just curious how these fonts, primarily Barlow, is able to render but it doesn’t appear to loaded into the project.
