/* REONE Live Voice: layout, call controls and ambience.
   Presentation only. Provider, VAD, lead capture, tools and conversation
   behaviour live in 17-live-voice.js and are not touched here.

   Three zones, so the controls can never scroll out of reach:
     header (badge, minimize)
     body   (hero, orb, status, captions, suggestions); the only part that scrolls
     dock   (session timer + call controls), always visible
   Every colour derives from the published theme tokens, so a Control Center
   palette (e.g. violet + lime) carries through without a code change. */
