/* Filtry listingu. */

/*
 * Bylo: cztery grupy rozwinite na stale, razem ~40 pigulek miedzy okruszkami a siatka.
 * Jest: jeden rzad nazw grup; lista opcji wysuwa sie NAD tresc (`position: absolute`),
 * wiec otwarcie filtra nie spycha produktow w dol. Mechanika siedzi w `details/summary`,
 * czyli w przegladarce — modul nie dokłada JavaScriptu do obslugi rozwijania.
