/* --------------------------------------------------------------
   Khromosome — HUD design system
   Deep navy + electric cyan; Inter + JetBrains Mono + Major Mono Display.
   Notched buttons, corner brackets, scanlines, grain — heads-up-display feel.
   Mirrors jdunn7/khrome — shared across every *.khromosome.network surface.

   File name retained as khrome-luxury.css to keep link refs stable; contents
   are now the HUD palette, not the prior fire/luxury theme.
