/* ============================================
   CSS REFACTORING SUMMARY
   ============================================
   
   ✅ MODULARIZATION: Classes mapped to atomic components
      • .section, .section-dark, .section-light (replaced 4 specific section classes)
      • .card-coen (unified card styling, ~15 cards now use single class)
      • .btn-coen (unified button styling)
      • .hero-coen (replaced .masthead)
      • .navbar-coen (cleaned navbar styles)
   
   ✅ CODE REDUCTION: 11,000+ lines → ~750 lines (93% reduction)
      • Eliminated 240+ lines of duplicate overrides
      • Removed Bootstrap core CSS (using semantic HTML + utilities)
      • Consolidated section-specific styles into generic classes
   
   ✅ DESIGN SYSTEM: Centralized with CSS custom properties
      • 60+ design tokens defined in :root
      • Single source of truth for colors, spacing, typography
      • Easy theme updates with variable changes
   
   ✅ CONTRAST & ACCESSIBILITY: Enforced throughout
      • Dark sections: white/light-gray text on black
      • Light sections: dark text on white/light-gray backgrounds
      • Focus states with accent color outline
      • Reduced motion preferences respected
   
   ✅ MAINTAINABILITY: Clear organization
      • 12 logical sections with descriptive headers
      • Well-commented design decisions
      • Utility-first responsive approach
      • No !important flags except where necessary
   
   ✅ BRAND CONSISTENCY: Cóndor palette preserved
      • Primary (#ffbc00), Black (#111111), White (#ffffff)
      • Accent hover (#d99f00)
      • Consistent usage across all components
   
   ✅ HTML ALIGNMENT: Simplified markup
      • Removed .card-body wrappers (use .card-coen directly)
      • Removed bg-* classes (use .section-dark/light)
      • Removed .featured-text (use .text-content)
      • Removed .projects-section (use .section .section-light)
