   ai_calendar_modal.css — Kalender-spezifische KI-Stiele
   ───────────────────────────────────────────────────────────────
   Das Grund-Styling (ai-modal-card, ai-message-bubble, Chips, Mic,
   Quota etc.) kommt aus ai_modal.css — die Klassen wurden bewusst
   wiederverwendet, damit es kein Duplikat-Styling gibt.

   Hier nur:
     1) .cal-ai-btn — Toolbar-Button im Kalender (Desktop + Mobile)
     2) .ai-cal-evpreview-* — Termine-Liste vor dem Speichern
