 * Cinematic hero: <img> u .hero__media, overflow hidden, keyframe zoom + drift.
 * Parallax: .hero__parallax dobiva --hero-parallax-x/y iz cmrok-hero.js (max 10px).
 *
 * Brzina i pomak: sve se podešava na .hero (inline style ili u CSS-u):
 *   --hero-anim-duration     trajanje jednog smjera (alternate = tamo-nazad)
 *   --hero-anim-timing       npr. ease-in-out, linear
 *   --hero-drift-x-start/end, --hero-drift-y-start/end  translate u % (ili px)
 *   --hero-drift-scale-start/end  zoom (bez jedinice, npr. 1 i 1.1)
 *   --hero-object-position-x/y, --hero-transform-origin-x/y  kadar i ishodište zooma
 *   --hero-parallax-max  max pomak miša u px (čita cmrok-hero.js)
