/* ==========================================================================
   NJY Technology — strona główna (PL i EN)
   Księga znaku NJY Technology 1.0 (09.2026), kierunek „Linia pióra":
   dzień i papier, litery „njy" monolinią, kropka nad j w Zieleni NJY.
   Jedyna grafika marki to linia pióra — jedna ciągła kreska tą samą
   grubością co litery, tylko poziomo i pionowo, z zaokrąglonymi narożnikami,
   z przystankami (puste kółka) i zieloną kropką na końcu jako wynikiem.
   Na zieleni zawsze stoi Noc (7,3:1), zieleń w tekście to Las (6,0:1).

   Kolejność: tokeny → reset → typografia → linia pióra → nawigacja → hero
   → sekcje (co robimy, problem, porównanie, kalkulator, proces, zasady,
   dla kogo, kontakt) → stopka → odsłanianie → RWD → ruch → druk
