/**
 * DRV Admin - Layout System Styles
 * Datei: 127-drv-admin-layout.css
 * Version: 2.0.0
 * Datum: 2026-01-10
 * 
 * Styling für das Admin-Layout mit horizontaler Navigation oben (fixiert beim Scrollen)
 * 
 * CHANGELOG v2.0.0:
 * - Navigation von Sidebar links zu horizontaler Top-Navigation geändert
 * - Navigation fixiert oben beim Scrollen (position: sticky)
 * - Content-Bereich nimmt volle Breite ein
 * 
 * CHANGELOG v1.1.0:
 * - Responsive Layout verbessert
 * - Content-Bereich scrollbar gemacht
 * - max-width entfernt, damit nichts abgeschnitten wird
