/* STARS NETWORK · /campaign
   The campaign journey, told as a route. A title split round the record; one
   long pinned act that travels sideways through the four stops (the copy
   rides the route with the scene, a rail below keeps the place); then the
   brief, set out like a printed sheet whose index ticks off as it fills. */
