Arena — memory grid
Cells coloured by their last writer; white pips are running processes.
Territory & population over time
Filled areas = share of the arena each player holds (left axis). Lines = live process count (right axis). Shared cycle axis.
Life-check ring
Each dot is a process; it drifts outward as it goes silent, and is culled if still past the ring when a check fires.
