/* Orion Defense Solutions
   Palette is derived from the logo navy. --navy is the logo colour itself;
   it is too dark to read as text on the near-black page, so it is only used
   as a fill behind white text. --accent is the same hue lifted for type,
   links, and focus rings. Copper only appears in the hero board. */
