/* Wygląd wizytówki STL. Teksty są w plikach HTML.
   Krój: Geist i Geist Mono (darmowe, licencja OFL, plik assets/fonts/OFL.txt).
   Wzorzec https://x.ai/changelog/bot składa tekst krojem xVf.
   To pismo jest własne i nie wolno go tu wgrać. Geist jest wolnym odpowiednikiem
   z tej samej pary co Geist Mono, którego ta strona używa przy etykietach.

   KOLORY — Marcin podmienia tylko liczby w bloku :root poniżej.
   Niżej w pliku nie ma wpisanych kolorów, są same zmienne.
   Żeby zmienić całość, wystarczą --color-bg, --color-ink, --color-muted i --color-line.
   Przycisk podąża za --color-ink. Inny kolor samego przycisku: nadpisz --color-button. */
