Zakladki wyszukiwarki nie zaslaniaja juz korzysci w hero

Sekcja hero miala sztywna wysokosc 700 px, a naglowek skaluje sie z szerokoscia okna
(clamp do 78 px). Na monitorach od ok. 1860 px rzad korzysci schodzil nizej i wchodzil
pod panel wyszukiwarki, podciagany o stale 194 px od dolnej krawedzi hero.

Wysokosc hero wynika teraz z tresci (min-height zamiast height) plus dolny odstep
210 px = 194 px podciagniecia panelu i 16 px przeswitu. Odstep jest staly niezaleznie
od szerokosci okna; ponizej 1760 px nic sie nie zmienia.

Test mierzy nachodzenie na siedmiu szerokosciach od 1280 do 2560 px.
