/* ==========================================================
 * Homepage hero slider ONLY (.zz-hero / .zz-hero-slide / etc).
 * Distinct from .zz-page-hero, which is the internal page-title
 * banner (About/Operations/Projects/etc) and is NOT touched here.
 *
 * Fixed explicit height per breakpoint (not aspect-ratio): the slide
 * image fills that height completely via width/height:100% +
 * object-fit:cover, so there is no way for a gap to appear between
 * the image and the container edge regardless of the image's own
 * natural proportions.
