   Kayts — marketing site
   Design system: deep navy ink + cool paper backgrounds, built
   around the brand mark's two colors — electric blue as the
   primary accent, lime as a secondary pop reserved for dark
   sections. Manrope display type over Inter body copy.
   Deliberately avoids the generic purple-gradient / stock-
   illustration SaaS template look.
