   tokens.css — every colour, size and timing in one place.

   Brand colours are sampled from the official logo:
     navy   #0A0E9C  left arc of the "a", the dark gem facet
     blue   #0048A9  the stem of the "a"
     sky    #0270B4  the bowl of the "d", the right gem facet
     purple #8805A9  the "d" and the gem
     amber  #F1AC17  the tittle and the lower arc
     rust   #C56021  the centre gem facet
   The hero photograph sits on a flat #1F1F1F, which is also --night.
