   otoCMS — arkusz stylów

   Kierunek graficzny „Rozstrzał”: strona firmowa pokazana jak rysunek
   techniczny w widoku rozstrzelonym — cztery płyty (treść, wygląd, silnik,
   serwer) ułożone jedna nad drugą. Każda warstwa ma własny kolor i ten kolor
   wraca w całym serwisie: w znacznikach rozdziałów, w szynie z postępem
   lektury, w tabeli kosztów. Pomarańcz rodziny „oto…” (#F37021) jest kolorem
   warstwy „treść” — tej, za którą odpowiada firma.

   Kroje: Bricolage Grotesque (zmienny, 300–800, oś optyczna) do tekstu
   i nagłówków, JetBrains Mono do etykiet i numerów. Oba hostowane lokalnie.

   Kolejność: kroje → tokeny → reset → typografia → układ → nagłówek → hero →
   spis → szyna → rozdziały → komponenty rozdziałów → zakończenie → stopka →
   responsywność → ruch → druk.
