/*
assistant.css

QUOI : Styles du widget conversationnel de l'assistant IA (bulle flottante + panneau de chat) — bulles de
       message, indicateur « réflexion », cartes d'événements cliquables et états d'erreur.

COMMENT : S'appuie sur les variables `:root` de style.css (chargé avant) avec valeurs de repli `var(--token, …)`
          pour rester robuste partout. Position fixe (bas-droite) ; panneau ancré au-dessus de la bulle en
          desktop, feuille quasi plein écran + voile en mobile. Animations désactivées sous `prefers-reduced-motion`.

OÙ : Chargé par `_site_header.html.twig` (cache-busté via `asset()`), couplé à `_assistant_widget.html.twig` et `assistant.js`.

POURQUOI : Un accès discret et engageant à la recherche d'événements rédigée par l'IA, cohérent avec la charte
           graphique du site, sans dépendre d'un framework CSS.
