/* 
 * Mobile-Friendly Dashboard Layout for ERPAthos
 * 
 * This CSS ensures all dashboard widgets/cards are stacked vertically
 * on mobile devices (< 768px) while preserving the desktop grid layout.
 * 
 * Breakpoints:
 * - Mobile: < 768px (stacked layout)
 * - Tablet: 768px - 1023px (partial grid)
 * - Desktop: >= 1024px (full grid preserved)
