/* GutterGuardHub Design System — LIGHT THEME
   Palette: deep teal-blue (water/protection, trustworthy) + leaf-green accent (the literal
   function of a gutter guard: keeping leaves out). White/near-white surfaces throughout —
   no dark header/hero. Typography: system font stack for performance (no webfont blocking). */
