 * Mobile-First Responsive Design
 * Based on Figma design (node 44:74)
 *
 * Architecture Principles:
 * ✅ Mobile-First (320px base → progressive enhancement)
 * ✅ NO fixed heights (content determines size)
 * ✅ Flexbox/Grid layouts (NO absolute positioning)
 * ✅ Shared components (navigation.css, footer.css imported)
 * ✅ CSS Custom Properties (Design Tokens)
