   CSS Architecture: Minimal Utility System
   
   Why not Tailwind?
   - Keeps theme dependency-free (no build step required)
   - Smaller footprint for simple sites
   - Easy to customize without tooling
   
   Why not Bootstrap?
   - Too heavy for this use case
   - Encourages over-styling
   
   This approach:
   - Small set of utility classes for common patterns
   - BEM-style component classes for specific UI
   - CSS custom properties for theming
   - Mobile-first media queries
