/**
 * Split hero — copy on the left, product compositions on the right.
 *
 * Loaded by hifocus_hero_media_assets() (inc/hero-media.php) only on a target
 * page that has hero images set. Every class is new (.hf-hero…); nothing here
 * restyles .sw-hero, .pos-hero or .net-hero, so a page without images keeps
 * its original hero exactly.
 *
 * Grid areas, desktop:      (spacer) | visual
 *                           intro    | visual
 *                           cta      | visual
 *                           (spacer) | visual
 * Stacked (≤1080px):        intro / visual / cta
 *
 * Crossfade is CSS only. The stack carries --hf-n (image count), each image and
 * dot carries --hf-i (its index). All share one keyframe cycle of n × 6s, and
 * each is offset by (i − n) × 6s, a negative delay, so image 1 is fully shown
 * on first paint and the others wait their turn.
