   2. Height chain: section → carousel-items → flickity-viewport

   KEY: .flickity-viewport height MUST NOT use !important.
   Flickity's adaptiveHeight sets viewport.style.height via JS (inline style).
   CSS !important beats inline styles → viewport collapses to 0 → black screen.

   Fix: give .carousel-items an explicit 100vh so height:100% on the
   viewport resolves correctly on desktop; let adaptiveHeight win on mobile.
