/**
 * Slavens Hero Slider — front-end styles.
 *
 * Center-mode carousel: the active slide sits spotlit in the middle while
 * the previous / next slides peek in at the edges, dimmed. Everything is
 * driven by CSS custom properties so settings (and themes) can override:
 *
 *   --slvn-accent        brand accent (CTA, active dot)
 *   --slvn-aspect        desktop aspect ratio, e.g. 16 / 5
 *   --slvn-aspect-m      mobile aspect ratio
 *   --slvn-min-h         minimum slide height
 *   --slvn-max-w         max width of the spotlight slide
 *   --slvn-peek          edge preview width, desktop
 *   --slvn-peek-m        edge preview width, mobile
 *   --slvn-dim           how dark edge slides are (0–0.9)
 *   --slvn-speed         transition duration
 *   --slvn-font-display  headline font stack
