Due to questionable privacy policy of Google Fonts (including them being
called illegal by the Munich court [1]), I have decided to self-host the
fonts. I have used the google-webfonts-helper[2] to load the subset
version of the font.
I have also added the `local()` source so that the font will not be
loaded if the user has a font with the same name installed on their
system.
After this commit, toot requires no 3rd-party resources any more 🎉
