The issue describes a hexagonal board for a Catan-like game with 19 hexes arranged in a circle, 30 outer line segments, and ports placed on some segments. It references a Catan spectator project. Start by examining the linked repository to understand existing board representations. Determine how to store hex positions, line segment locations, and port assignments. The work involves designing a data structure, not implementing a specific fix.
