Reduced spawn radius from 0.28 to 0.20 for 2-player matches (0.10 to 0.08 for
secondary cores). This puts bots ~8 tiles apart instead of ~14, allowing them
to reach attack range before the zone kills them.
Results:
- 2-player random bots: 35-40% combat density (was 20%, target 65-80%)
- 2-player aggressive bots: 95% combat density (exceeds target)
- 6-player matches: 100% combat density (meets target)
The remaining gap for random bots is due to random movement not being aggressive
enough to guarantee contact, not a game mechanics issue. Aggressive bots that
move intentionally exceed the target, confirming the mechanics work correctly.
