   ZHU Elektromax — style projektu
   Bootstrap 5 (assets/bootstrap.min.css) jest bazą layoutu; ten plik dostraja
   zmienne, typografię i komponenty własne. Sekcje nie mają sztywnych
   wysokości — rosną wraz z treścią; typografia skaluje się płynnie przez
   clamp(), więc układ działa poprawnie od ~360 px do dużych desktopów.
