   Statystyka24 — Interfejs V2 (alternatywny, testowy)
   Plik: assets/css/stat24-v2.css

   Reużywa tej samej palety kolorów co stat24.css (ciągłość wizualna
   z resztą strony), ale wprowadza nowy, krokowy układ z wyszukiwaniem
   i grupowaniem testów. To NIE nadpisuje stat24.css — oba pliki
   ładowane są razem, bo część wnętrza (parametry, wyniki, sklep)
   nadal korzysta z klas .s24-* zdefiniowanych w oryginalnym pliku.
