/* Playground page.
   Implements Figma wC5383GSncabfPynmGpSzw node 820:19667 (1280 x 1463).
   Loaded after landing.css, which supplies the tokens, body, grid canvas,
   stage and nav shell.

   Two halves that want different things. The art frame is a composition, so
   it keeps the site's fixed-frame treatment and its cqw coordinates. The
   creative zone is a tool, so it runs in normal flow down the same 1030
   column the case studies use — the frame only ever placed a heading in it,
   and pinning a canvas and its controls to frame coordinates would fight
   every screen that is not exactly 1280. */
