Tower Defense Power Grid (relays, light beam, night)

A GameSkill original: towers fire only while linked to the power source through relays, a fixed capacity is shared in a stable order so new towers never black out old ones, selling recomputes and reports a brownout, a movable light beam adds damage and slow, and at night towers need light to see far.
