/* BeepSweep public voice-demo — self-contained, on-brand (obsidian tokens), embeddable.
   DARK is the default — matches beepsweep.com (obsidian / graphite / amber).
   ?theme=light forces the light Hearth skin.
   ?embed=1 → JS adds html.embed, hiding site chrome for seamless iframe use.
   Layout = viewport-height app-shell: only the live transcript (or summary) scrolls
   internally. Document never scrolls in embed mode — iOS scroll-trap fix. */
