/* Strona główna serii — wygląd z powłoki projektów (tło, szkło, akcent #4cc9f0, nagłówki Space Grotesk), bez kopiowania
   całej powłoki. Nagłówki: Space Grotesk hostowany samodzielnie (OFL, css/czcionki/); tekst: krój systemowy (lżej niż Inter,
   który w projektach dochodzi do ok. 130 KB). Karty: wąskie — obraz nad tekstem; szerokie (zapytanie kontenera) — obraz
   z prawej, wtapiany w tło karty jak na obrazach og serii. */
