   Desktop-first, as briefed. Mobile is *recomposed*, not stacked: the rails
   become swipe carousels, the coverflow becomes a peek-scroller, the hero
   re-orders so the wordmark still crops the section edge, and the offset
   card grid keeps its rhythm at two columns instead of collapsing to one.
