   Dekkjahúsið Tire Search — tire-search.css

   Design philosophy:
   - Light, airy, clean — easy on the eyes for all ages
   - Moss green primary accent (matches site's forest/green identity)
   - Strong typography hierarchy — size → brand → name → price
   - High contrast text on all backgrounds (WCAG AA+)
   - Generous touch targets (52px+) on every interactive element
   - No heavy dark blocks — grey tints only where needed for depth
