   Graphite + stone + the client's brand red (#e14024). The brief's earth-tone
   direction survives in the neutrals; olive was retired when the client
   supplied a real brand colour, because red-orange and olive-green are near
   complementaries and fight for the same attention.
   Ground is light because the real use scene is someone standing outdoors in
   Malaysian daylight, on a phone, in glare.
