/* PWA Specific Styles - Using AutoWash Design System */
/* 
 * This PWA stylesheet inherits from main.css and uses existing CSS variables
 * to maintain consistency with the AutoWash design system.
 * All colors, spacing, and styling should use existing CSS custom properties.
 * 
 * IMPORTANT: This file should NOT override main app styling or backgrounds.
 * It only adds PWA-specific functionality without changing existing design.
