 * ai-chat-public.css — Metrics Tools Public Chat (Landing Page)
 * Branch: public_chat
 *
 * Gleiche Optik wie ai-chat.css, aber:
 * - Kein .page-container / .footer push (kein Metronic-Layout)
 * - Panel als Overlay (kein Content-Verschieben)
 * - Kein Onboarding-Modal, kein Context-Bar, kein Mode-Toggle
 * - DSGVO-Hinweis im Input-Bereich
 *
 * Zum Löschen: diese Datei + ai_chat_public.php (View) + Public_chat.php (Controller)
 * und den Load-Call in homepage.php entfernen.
