/*
 * FRGMT_04 CSS - Optimized Architecture v2.0
 * ==========================================
 * 
 * FILE OPTIMIZATION SUMMARY:
 * - Original: 2,482 lines → Optimized: 2,396 lines (3.5% reduction)
 * - Phases Completed: Structure Consolidation, Component Deduplication, 
 *   CSS Variable Standardization, Performance Optimization
 * 
 * RESPONSIVE ARCHITECTURE:
 * - Single consolidated mobile block @media (max-width: 767px) at lines 1399-1832
 * - Nested breakpoints: 480px, 620px, 320px within main mobile block
 * - Tablet styles: @media (768px-1023px) at lines 2060-2122
 * - Desktop styles: @media (1024px+) at lines 2123-2191
 * 
 * CSS VARIABLE SYSTEM:
 * - Component Sizing: --button-height-sm through --button-height-2xl
 * - Button Padding Scale: --button-padding-xs through --button-padding-lg
 * - Font Component Scale: --font-component-xs through --font-component-xl
 * - Neural Spacing System: --space-xs through --space-2xl (8pt grid)
 * - Typography Scale: --text-xs through --text-4xl
 * 
 * COMPONENT ORGANIZATION:
 * 1. CSS Variables & Reset (lines 13-93)
 * 2. Neural Button System (lines 258-340)
 * 3. Neural Icon System (lines 388-453)
 * 4. Touch Interaction System (lines 453-464)
 * 5. Layout Sections (lines 465-730)
 * 6. Glitch Effects (lines 735-991)
 * 7. Audio Controls (lines 991-1131)
 * 8. Visual Effects (lines 1131-1176)
 * 9. Responsive Blocks (lines 1399-2191)
 * 10. Performance Optimizations (lines 2192-2396)
 * 
 * PERFORMANCE FEATURES:
 * - Optimized CSS specificity (reduced !important usage)
 * - Mobile-optimized matrix rain and scan lines
 * - GPU acceleration with transform3d and will-change
 * - Prefers-reduced-motion support
 * - Scroll performance optimization classes
 * 
 * MOBILE TOUCH OPTIMIZATIONS:
 * - 44px minimum touch targets (iOS guidelines)
 * - Touch-friendly card interactions
 * - Optimized matrix rain for mobile performance
 * - Responsive typography scaling
