/**
 * Facetten-Filter auf Kategorie-/Markenseiten (archive-filters.php).
 * Design-System v1.1: ruhig, wertig; Token --zcf-* (Fallbacks = Sollwerte §3).
 *
 * Redesign 2026-07-20 (Axel): weg vom Text-Dropdown, hin zu OFFENEN, visuellen
 * Facettenblöcken — Farbe als Swatch-Kreise, „Für wen"/„Einsatzbereich" als
 * Piktogramm-Kacheln, Rest als Text-Chips. Alles mit sichtbarem Häkchen/Ring,
 * additiv. Mobile-first: Blöcke stapeln, Optionen brechen um. Touch >= 44px.
