   1. FILTRY (RYCHLÉ A POKROČILÉ)
   ======================================== */

/* 
   POZNÁMKA: Následující sada stylů pro filtry je založena na souboru meridla.css.
   Původní soubor drzaky.css obsahoval mírné odlišnosti:
   - .filter-grid měl 'gap: 1.5rem' místo '1rem'.
   - .quick-filters měl 'gap: 0.75rem' a jiné odsazení.
   - .filter-tag:hover v drzaky.css měnil pouze barvu textu a rámečku, nikoli pozadí.
   Pro sjednocení byl vybrán vzhled z modulu Měřidla.
