   The DAG Band - design system
   --------------------------------------------------------------------------
   Deliberately NOT the solo site. davidalangraham.net is sand, sunset and
   sea - beach country, bright and warm. This is bourbon, denim and weathered
   cream: darker, heavier, built to read as a band rather than a songwriter.

   Type does most of the work:
     Anton      - hero and section heads. Condensed, enormous, poster energy.
     Newsreader - editorial serif for anything that needs warmth or authority.
     Inter      - UI and body. Neutral on purpose so the other two carry it.
