/* ---------- Demo: two Codex-style chat windows in staggered rows ----------
   Dark, like the Codex desktop app: a grey window on the black page, the user's message in a
   bubble on the right, each step a quiet one-line row that opens on click, and a composer at the
   bottom. OpenCrawl's cards carry the logo's static coral and cobalt edges. */
