   OPA OPA! — blog
   Ładowany PO style.css; korzysta z jego kolorów (ink, bone, sun, olive, saffron, sea).
   Granatowy pasek nagłówka i stopka jak na reszcie strony, treść na jasnym tle (sea),
   nagłówki szablonowe (Saira Stencil One), podtytuły kursywą (Cormorant Garamond),
   akcent grecki — meander pod nagłówkiem.
   Celowo bez klasy .section: main.js animuje każdą .section (opacity 0 do przewinięcia),
   a treść wpisu ma być widoczna od razu.
