   Standalone styles — žádný framework, žádný build step.

   Vizuální jazyk „Značka“:
   hluboké barevné pole nese hlavičku i hero, zbytek stránky je
   papír. Cyan je jediný akcent a mimo pole dostane jen linky,
   čísla a tlačítka. Jeden poloměr, jedna rozteč, žádné stíny
   na plochách — hloubku dělá barva, ne rozostření.
