/* Four|Nine
   Layout: a one-screen app. Fixed header; two side-by-side scrolling panels
   (Digital, Clients) — the active one is 70% wide with a masonry grid, the
   other 30% with a single column; pointing at a panel makes it the active one.
   About and the project page are full-width views that fade in.
   Films, photos and catalogues open in a full-screen viewer on top. */
