/**
 * Soubor: /assets/css/filter.css
 * Název: filter.css
 *
 * Účel:
 * Samostatný stylesheet pouze pro React filtr modelek.
 *
 * Tento soubor:
 * - styluje pouze stránku pokročilého filtru,
 * - je oddělený od hlavního /assets/css/frontend.css,
 * - používá scope přes #filter-root, aby nezasahoval do zbytku webu,
 * - zachovává vizuální kvalitu stávajícího filtru a pouze se dolaďuje pro nový modelingový frontend.
 *
 * Tento soubor nesmí obsahovat:
 * - admin styly,
 * - globální styly pro celý web mimo scope filtru,
 * - přepis filtru od nuly bez důvodu.
