   Ukrainian Water and Utilities — design system

   Light, institutional and engineering-led: the audience includes municipal
   clients, donors and IFIs, so the site reads as a technical dossier rather
   than a brochure. Water blue carries the brand; the Ukrainian yellow appears
   only as a small accent, never as a field.
