   Sarnia palette: the blue and charcoal sampled straight out of Logo.png,
   with a single warm accent reserved for calls to action.

   Every pair below was measured, not eyeballed. Contrast against white:
     primary        #0d4e8b   8.47:1
     primary-dark   #0a3d6e  11.02:1
     primary-light  #14639f   6.33:1   (worst point of the hero gradient)
     accent         #b8480a   5.29:1   (white button text, needs 4.5:1)
     accent-dark    #8f3707   7.30:1
     text           #23303f  13.41:1
     text-muted     #55647a   6.02:1
     heading        #16202e  15.35:1
