/* ── How it works: interleave copy + its card per step (mobile narrative) ──
   Desktop is a two-column pinned scroll story; the ≤1024 fallback stacked ALL
   copy then ALL cards (a disconnected ~4.5-screen double-read). On mobile,
   flatten both columns into one flex flow (display:contents) and ORDER each
   copy step directly above its matching demo card, so each step reads as one
   beat: explain → show. Cards are already position:relative on mobile, so
   order alone interleaves them; the inert stepper stays hidden. */
