   KiwiSystems AI -- design system (v2, "futuristic AI" direction)
   Near-black surfaces with a cyan-to-violet accent gradient, glassmorphic
   panels, and a faint circuit/grid backdrop. Space Grotesk carries brand
   and heading moments (geometric, technical character); Inter carries
   body/UI text; the existing monospace stack still carries code.
