/**
 * QuickBio Liquid Glass Design System
 *
 * A glassmorphism design system with OKLch colors, backdrop-blur effects,
 * and comprehensive accessibility support.
 *
 * Features:
 * - Light/Dark mode via CSS variables
 * - Supports both media query (prefers-color-scheme) and class-based (.dark) switching
 * - Syncs with dashboard localStorage theme via `qb_theme` key
 * - Accessibility: reduced-transparency, high-contrast, reduced-motion support
 *
 * Key Classes:
 * - .glass, .glass-card - Glassmorphism containers
 * - .glass-nav, .glass-nav-scrolled - Navigation bar
 * - .bg-gradient-mesh - Animated gradient background
 * - .btn-gradient - Gradient buttons
 * - .logo-adaptive - Makes logos white in dark mode
 * - .text-foreground, .text-muted - Theme-aware text
 *
 * Usage: Load this CSS AFTER Tailwind CDN to override with design tokens.
 * <link rel="stylesheet" href="/css/liquid-glass.css">
