/* Fonty hostowane lokalnie — Fraunces, Hanken Grotesk, JetBrains Mono (SIL OFL 1.1).
   Zmienne (variable) kroje, podzbiory latin i latin-ext. Plik wygenerowany z
   Google Fonts css2; patrz public/assets/fonts/LICENSE.txt.

   Pliki są dodatkowo obcięte (fontTools): oś wagi zawężona do grubości, które
   arkusz naprawdę zamawia, znaki do zakresu ASCII + Latin-1 + Latin Extended-A
   (czyli cała Europa Środkowa, żeby nazwiska w panelu nie traciły ogonków)
   plus typografia, a z tablic OpenType zostały kern, ligatury i znaki
   diakrytyczne. Razem 224 KB → 93 KB. Fraunces jest przypięty do wagi 500,
   bo tylko w takiej występuje — nowy nagłówek w innej grubości trzeba będzie
   wygenerować od nowa, inaczej przeglądarka pogrubi go syntetycznie. */
