  Responsive visible slides — driven by the carousel's OWN width via
  container queries (and mirrored in JS via carousel.offsetWidth):
    ≥ 900 px  →  4 slides
    480–899 px →  2 slides
    < 480 px   →  1 slide

  Slide width formula:
    width = (container - (N-1) × gap) / N   where gap = 16px

    1 slide: calc(100% - 16px)   [8px breathing room each side]
    2 slides: calc(50% - 8px)
    4 slides: calc(25% - 12px)
