/* System Duo home: the rhythm below the masthead. "Try it", "Ways in" and "Models" keep their dotted bands; between
   them, Architecture and the full stack sit on bands of blocks (assets/sections.js) that rise out of the paper and
   dissolve back into it block by block. The mission's dusk closes the day. Cards and code keep their own solid
   surfaces above all of it. */
