   WARIANT E — „Zmierzch"
   Materialna głębia. Warstwy niemal-czerni, miękkie krawędzie,

   SIGNATURE: strona rozjaśnia się z każdą sekcją (l1 → l7).
   Najjaśniejszy punkt całej strony to kontakt — miejsce, w którym
   piszesz wiadomość. Stopka wraca do najgłębszej czerni, żeby
   kontakt został szczytem, a nie przypadkiem.
