/**
 * Pit o Cuixa — Menu Slider + Fallback Hero Styles
 *
 * BEM component for the image slider (`menu-slider`) and the
 * CSS-only decorative fallback (`menu-hero--fallback`).
 *
 * Slider uses `translateX()` + `transition: 0.4s ease` — no JS animation lib.
 * @media (prefers-reduced-motion: reduce) → instant transitions + no autoplay.
 *
 * @package Pit\Cuixa\Frontend\Styles\Components
