/* ==========================================================================
   SupDucks Arcade — play.supducks.com

   Self-contained. The tokens, base, layout, buttons, header, footer and page
   head are copied from supducks.com's assets/css/styles.css so the arcade
   reads as part of the same site; the cabinet comes from the scrapped
   in-site arcade; the worlds section is new.

   Sections:
     1. Tokens            6. Footer
     2. Reset / base      7. Page head
     3. Layout            8. The arcade cabinet   (A. arcade games)
     4. Buttons           9. The big worlds       (B. linked-out games)
     5. Header           10. Responsive / motion
