I'm sorry, I was very tired when I made the ticket. Here is why I think the TTF-files should be replaced by web fonts, which should have been in the ticket from the start.

The current fonts in the assets repository are in the TrueType Font (TTF) format, which is an older standard primarily used for operating systems and desktop applications. To enhance the web experience for people visisting, these should be replaced with web fonts in the WOFF2 format.

WOFF2 files are specifically optimized for the web, offering advantages such as compression that results in smaller file sizes. This optimization not only improves loading times but also contributes to a better user experience and enhanced SEO performance.
