+"""Shared core for the shepherd herding project.

+This package is the single source of truth for world geometry, sheep
+flocking dynamics, differential-drive kinematics, observation building,
+and the Strömbom heuristic. It is imported both by the Webots
+controllers (for inference) and by the Gymnasium training environment
+(for fast PPO rollouts), so the two paths cannot drift apart.
