   also the wrong axis: it made the cover art look like four different sites

   Instead --art-hue only chooses a POSITION along the brand ramp, between
   --brand-accent (ember) and --brand-accent-2 (flare). Every generated cover

   per beat, and still follows the admin theme editor for free. */

     how deep the shadow runs, and which way the base gradient rakes. Records
