   CODYNIX LTD — Design System
   Palette: Navy (dominant), Royal Blue, Signal Red, Paper White
   Type: Manrope (display) + Inter (body)
   Signature motif: the "flight-line" — a 12° diagonal cut used
   in the logo, section dividers and hero UI, a quiet nod to the
   Union Jack's diagonals without ever showing the flag itself.
