/* ---------- Module motion: scroll reveal + hover spotlight ----------
   Shared by every "module" (cards, spec sheets, steps, CTA band,
   contact panels) and the headings between them:
   1. Scroll reveal — JS tags each item [data-reveal] and flips it to
      .is-visible via IntersectionObserver on first viewport entry.
   2. Hover spotlight (modules only) — hovering one blurs/dims its
      siblings within the same parent.
   Both degrade to a static layout without JS, and are neutralised for
   prefers-reduced-motion by the global override above. */
