/* =========================================================================
   Muster-Demo v2 — KI-Anfrage-Assistent (Chat-Widget, premium)

   Der Assistent ist der Star: Launcher «kommt zum Leben» (Pop-in + Puls),
   pulsierender Online-Indikator, Teaser-Blase, sanft animierte Nachrichten,
   immer sichtbarer «Gespräch beenden»-Button.
   Farben kommen aus den --chat-* Tokens des jeweiligen Themes (theme.css).
   Mobil-first, Touch >= 44px, AA-Kontrast, reduced-motion respektiert.
