/* ── Hero demo ───────────────────────────────────────────────────
   A scripted example conversation in place of the old video loop. The
   finished conversation is in the HTML, so JS-off and reduced-motion
   visitors see the end state; js/hero-demo.js replays it when motion is OK.
   It sits in a device: a monitor on wider screens, a phone at 640px and
   below. The bezel flips with the theme so it always contrasts the page;
   the screen stays dark green in both. */
