   WYCENA — wspólny motyw dla podstron modułu nieruchomości
   (nieruchomosci.html, oferta.html, admin.html)

   Zmienne, nawigacja, przyciski, nagłówek strony i stopka — identyczne jak
   w index.html, żeby całość wyglądała spójnie. Plik jest wspólny i
   cache'owany przez przeglądarkę, więc kolejne podstrony ładują się szybciej.
