/* Dekoracyjne kółka tła USUNIĘTE 2026-08-06 (polecenie właściciela: czyste tło).
   Usunięty razem z nimi `@keyframes float` — po zniknięciu `.shape` nie miał ani jednego
   użytkownika (sprawdzone grepem), a martwa reguła animacji to dokładnie ten rodzaj
   pozostałości, który później nikt nie umie bezpiecznie skasować. */
