   Palette taken from the Destech logo: orange mark on charcoal.

   Two oranges on purpose:
     --brand   #FF6B00  the true logo orange. Graphics, and text on dark only —
                        it is 2.9:1 on white, which fails accessibility for text.
     --accent  #C24E00  a deepened brand orange for links, buttons and small
                        text on white. 4.8:1, passes WCAG AA.
