   SECTION MONSTERS – HeroAI-Chat & Terminbuchung
   css/heroai.css

   CHAT (.hai-*): 1:1 dieselbe Optik wie der HeroAI-Chat in der App
   (app.section-monsters.de, css/hero-ai.css) – helles Panel, violetter
   Verlauf im Kopf, graue Bot-Blasen. Die Tokens sind bewusst identisch
   übernommen, damit beide Oberflächen nicht auseinanderlaufen.

   TERMINBUCHUNG (.tb-*): sitzt im dunklen Demo-Bereich der Landingpage
   und nutzt daher weiter die dunklen Tokens aus css/style.css.
