   min-height floor at >=40rem) with align-items:center, which previously
   centered a content-height slideshow — the image band (~211px) sat inside the
   388px hero leaving empty bands above/below. Stretch the viewport and let the
   track + active slide fill it so the absolutely-positioned hero image covers
   the full hero. On mobile the hero collapsed to padding-only (18vh+8vh) and
   clipped the CTA at its bottom edge; give it a source-parity height (41vh at
