/* Mobile-first návrh webu kongresu (2026-10-12).
 * Postup: impeccable / adapt (prispôsobenie = premyslenie pre palec a malú obrazovku, nie zmenšenie)
 *         ui-ux-pro-max (dotykové plochy ≥ 44 px, text ≥ 16 px, kontrast 4,5 : 1, mobile-first zlomy)
 * Základ platí pre telefón. Väčšie obrazovky sa pridávajú cez min-width (768 a 1024 px).
 * Farby, písmo a rozostupy sú z tokens.css (schválená identita); nižšie len úpravy pre kontrast a čitateľnosť.
