/* Skai Solutions - shared site stylesheet.
   Matches the homepage design system: dark nav and footer, light content,
   sky-blue accent (#0EA5E9), system font stack, white cards on #F8FAFC.
   Variable names keep their historic --purple* spelling so any inline
   var() references on existing pages keep resolving. */
