Teleport & Map Unlock

Build the fast-travel layer of an open-world game: how the map gets revealed, how the waypoint network grows, how a teleport executes, and what travel policy the game adopts. References: BotW/TotK (towers, 142 Travel Gates) and Genshin (638 waypoints, statues, multi-layer maps), with the Morrowind→Oblivion→Ubisoft-tower design lineage and Spider-Man/Rift Apart seamless tech.

The architecture rule

One unlock model, one waypoint registry, one teleport sequence — the map UI and the travel UI both derive from the same flags.
