   SmartFluent website styles

   Organization:
   1. Design tokens (light + dark themes)
   2. Base styles
   3. Layout helpers
   4. Shared components (buttons, cards, forms, badges, section heads, CTA box)
   5. Site navigation
   6. Site footer
   7. Page sections (home, ROI calculators, legal, contact form)

   Conventions:
   - Mobile-first; breakpoints: 768px (md) and 1024px (lg)
   - Colors are HSL triplets consumed via hsl(var(--token) / <alpha>)
   - Page-specific classes are prefixed: .home-*, .roi-*, .varoi-*, .legal-*
