   Parchment and ink, with the Ordnance-Survey-ish warmth the
   brand has carried since the first concept boards. Segment
   colours are the CONFIRMED hexes from the colour states sheet
   and must not be re-tuned for contrast here — the map is the
   product, and a line's colour is data, not decoration.
