/* ============================================================
   THE CROSSING · DxVida's own visual system.
   Not bands with eyebrows and cards. Full-height statements,
   the ground floods colour between them, and one continuous
   line crosses each screen from the problem side to the
   resolved side. The line is the mark: two loops meeting.
   No serif anywhere. The personal site owns Playfair; this
   one is one sans and the drawings carry the personality.
