/**
 * ampguard-assistent/assets/ampguard-assistant.css
 * ═══════════════════════════════════════════════════════════════════
 * Premium-Design für den AmpGuard Assistenten.
 *
 * Bewusste Design-Entscheidungen:
 * - Durchgehend HELLES Design (Header, Launcher, Chat-Fenster) - kein
 *   dunkles Glassmorphism, keine dunklen Flächen. Das ist bewusst so,
 *   damit der Assistent für alle Besucher (inkl. Sehbehinderung,
 *   Lesbarkeit bei Sonnenlicht auf Mobilgeräten etc.) gut lesbar
 *   bleibt: durchgängig dunkler Text auf hellem Grund statt heller
 *   Text auf dunklem Grund.
 * - Akzentfarbe var(--green) (mit Fallback), passend zum bestehenden
 *   CSS-System der Seite (siehe footer.php: border-top: 4px solid
 *   var(--green)). Dunkelblau (var(--blue)) wird nur noch sparsam für
 *   Text/Icons eingesetzt, nie mehr als Flächenfarbe.
 * - Ruhige Schatten statt harter Kontraste.
 * - Der Launcher steht standardmäßig rechts über dem WhatsApp-Button
 *   (der laut footer.php bei right:18px/bottom:18px, 48px Durchmesser
 *   sitzt), damit sich beide Buttons nicht überlappen.
 * - Ein einmaliger, dezenter Puls beim Laden lenkt Aufmerksamkeit auf
 *   den Launcher, OHNE dass sich das Fenster von selbst öffnet.
