   FILTRY, KARTY PRODUKTÓW I KATEGORII — "Quiet Luxury"
   Wspólny arkusz dla sklep.php i oferta.php (oba mają ten sam panel #filter-bar).
   Ładowany PO wbudowanych <style> stron, więc przy równej specyficzności wygrywa.

   Zasady języka wizualnego (jak w nowym menu górnym, _nav.php):
     • przyciski i etykiety = pigułki (border-radius: 9999px), panele i karty = 18–26 px
     • złoto #db821b / #f0c27a, szampan rgba(197,168,128,x) tylko w liniach i ramkach
     • listy rozwijane w ciemnym "bazalcie" (#1d1b19 → #131211), tekst ciepła biel
   Świadomie tylko CSS — logika filtrowania (zastosujFiltry, custom-dropdown,
   .flt-active, renderujAktywneFiltry) zostaje nietknięta.
