/* Michael Beglinger, static rebuild of the Squarespace site.
   Desktop values (>= 768px) follow the live site, which scales linearly with the viewport width.
   Below 768px the live site freezes the type scale at its 900px values; spacing follows the live site too.
   Header, mobile menu and footer follow the approved artboards (HANDOFF.md, sections 5 and 7). */
