   The brand green is sampled from the logo artwork: #02BC6B.

   It sits at 2.5:1 against white, which is below the 4.5:1 needed for body
   text, so on light sections it is only ever used as a FILL (buttons, rules,
   bars) with dark text on top. Green *text* on white uses --green-text.
   Against --ink it reaches 7.8:1 and is used freely.
