/*
 * Wizytówka Adama Grudzińskiego.
 *
 * Ciemna, jedna decyzja na całą stronę: kolor wnoszą wyłącznie zrzuty produktów,
 * interfejs jest z grafitu i jednego ciepłego akcentu. Bez kafelków i ramek:
 * sekcje rozdziela światło i cienka linia, a nie pudełka.
 *
 * Typografia: Bricolage Grotesque w nagłówkach (ma charakter i polskie znaki),
 * Inter Tight w tekście. Jeden promień narożnika (14 px) dla obrazków,
 * pigułki tylko dla przełącznika języka i plakietek technologii.
