/* ===== FONTS =====
   Inter is self-hosted rather than loaded from fonts.googleapis.com. A page whose
   whole argument is "nothing leaves your device" should not hand every visitor's IP
   address to Google before the first paragraph renders. Self-hosting is also what
   lets the privacy policy's website section make a flat claim instead of a hedged one.

   Inter v20 ships as a variable font, so one file covers every weight the site uses
   (400/500/600/700/800) — hence the `font-weight: 100 900` range rather than five
   separate @font-face blocks. latin-ext is here for the Slovak diacritics in the
   company name. Files came from Google's own CDN and are SIL Open Font License 1.1. */
