/**
 * kundenberaterin.css — Voice-Bot Overlay (Wi.Fo!-Lab Design System)
 *
 * Single-File-Stylesheet für das Plugin-Frontend. Enthält:
 * - Design-Tokens (Farben, Typo, Spacing, Radii, Shadows, Motion)
 * - Komponenten: FAB, Modal mit Brand-Frame, Header, Chat,
 *   Tool-Pills, Produkt-Carousel, Quickstart-Chips, Input-Dock,
 *   Voice-Wave + Text-Card, Error-Banner, Orb-Container
 *
 * Klassen-Präfix: .kb-* (alle Selektoren scoped, kein Element-Selektor
 * außerhalb von .kb-modal-root).
 *
 * Z-Index-Bereich: 9998 (FAB) / 9999 (Modal) — verträglich mit den
 * üblichen Cookie-Bannern (~9000).
 *
 * Schriften: Nunito + Nunito Sans. Werden via <link> im PHP-Inject
 * geladen (FrontendInject.php), nicht via @import (FOUT vermeiden).
