/* ============================================================
   V12 — ATLAS
   The branch as one lit node in a worldwide network. Every page
   alternates a dark "night map" register (the network graphic,
   coordinates, the wide view) with a plain paper register (the
   content itself). No raster imagery, no invented branch counts
   or locations on the map — the network stays deliberately
   abstract; only verified facts (founding year, cities, "first
   multi-city branch", real Delft/Rotterdam coordinates) get
   stated as claims.
