/**
 * =====================================================
 * Sosyotik Design System v3.0 — Layout Module
 * Top Navigation Header + Footer
 * Mobile-First Responsive Architecture
 * =====================================================
 *
 * Inspired by: Linear, Vercel, Stripe, Notion, Clerk
 * Architecture: Fixed top-nav → content → footer
 * NO sidebar — everything is top-aligned
 * Mobile-first breakpoints: 768px, 1024px, 1200px
 *
 * Z-Index uses DS scale:
 *   Header: --ds-z-sticky (200)
 *   Dropdowns: --ds-z-overlay (500)
 *   Mobile Nav: --ds-z-modal (1000)
 *   Toast/Confirm: --ds-z-toast (1500)
