/* ==========================================================================
   RISE THE NATION — THE HALL
   Built from the flyer: an empty concrete hall, one hard shaft from the
   roof, thick smoke, and a crowd standing dark against a blown-out wall.
   The light is BEHIND the people, not on them — everything here is rim and
   silhouette. No warm colour anywhere; the room is cold and the costumes
   are the only colour that survives.
