/*
 * ChallengeX Design System CSS
 * Based on ChallengeXTheme.swift - 100% faithful reproduction
 * Created by Sébastien Kothé on 26/05/2025
 * 
 * PERFORMANCE OPTIMIZATIONS:
 * - backdrop-filter usage minimized for better mobile/low-end device performance
 * - Only modal overlays retain reduced blur effects (3px-6px instead of 5px-10px)  
 * - All frequent elements (inputs, snackbars, table wrappers) use solid rgba backgrounds
 * - Mobile devices: all backdrop-filter disabled for smooth scrolling
