/* Chatbot Stylesheet
   EW Sirnach AG, Ueli Kienholz, 10.10.2025, 19:16
   Dieses CSS funktioniert fuer beide Websites (ewsirnach.ch und co2ready.ch)
   Fuer co2ready.ch sollte allerdings vor dem Deployment die Kontanten 
    (s. gleich unten im Abschnitt :root)
    --button-bottom und 
    --button-right
    angepasst werden
