/**
 * Universal Navigation Styling - All Themes/Concepts
 * Created: 2025-10-21
 * Purpose: Standard navigation across all header concepts
 *
 * UI/UX Expert Guidelines Applied:
 * - Compact top navigation (smaller toggle = shorter bar)
 * - Mobile: 44px minimum touch targets (Apple/Google standard)
 * - Generous spacing for comfortable navigation
 * - Left-aligned menu items (easier to scan than centered)
 * - Visual separation between items
