# US-002: Unlock Base II navigation

As a **player with Base I**, I want visual guidance toward my base so that I can find it without relying on coordinates.

## Acceptance criteria

- [ ] Base II requires Base I and an established base.
- [ ] Base II unlocks at a configurable cumulative grass-or-dirt threshold that defaults to 500 blocks, 250 more than Base I.
- [ ] Base II provides particle-based navigation and does not grant or require a physical compass item.
- [ ] While enabled and in the base's world, particles are drawn along the ground to indicate the direction toward the base.
- [ ] Particle generation is bounded to avoid excessive server or client load.
- [ ] A player in another world receives a clear message instead of a misleading particle direction.
- [ ] `/basenavigation` toggles guidance on and off after Base II is unlocked.
- [ ] The navigation preference persists across reconnects and restarts.
