   Relied — interface system
   --------------------------------------------------------------------------
   Deep space surfaces, a cyan rim light and an electric-blue fill, cut-corner
   panels and hairline geometry. Type does the heavy lifting: Space Grotesk for
   display, Inter for prose, a monospace for labels and data.

   Everything is token-driven; components only reference the tokens below.
   Angular shapes come from clip-path cuts and 1px rules, never from images.
