/*
 * =====================================================
 * BFS Mobile Optimization
 * =====================================================
 * Eine Datei, die alle Mobile-Anpassungen abdeckt.
 * In jeder HTML-Datei einmal verlinken — fertig.
 *
 * Strategie:
 * - Nicht das Design auf dem Desktop ändern
 * - Nur dort eingreifen wo Mobile-Geräte (≤768px / ≤480px) leiden
 * - Hamburger-Menü statt versteckter Navigation
 * - Schriften proportional kleiner
 * - Grids/Tabellen einspaltig stapeln
 * - Buttons vergrößern (mind. 44px Touch-Target)
 *
 * Reihenfolge: Diese Datei MUSS *nach* den Original-Styles
 * geladen werden, damit die Mobile-Regeln greifen.
