/* ============================================================
   CCA School OS — Brand Design System
   Two brand colours, taken from the CCA crest:
     Orange  #E0501F   (primary action / accent)
     Blue    #0860A8   (secondary: sidebar, links, info)
   (The darker navy and lighter blue shades were removed.)
   Everything else is neutral (greys) or status (green/amber/red).
   This file is the single source of truth — every module
   uses these tokens; never hard-code colours elsewhere.
