`strategies` described a stance blended over hand-scored intents, which is the design the evening's measurements retired: a parallel scoring system to the feature basis, defence discounted by a hard-coded half, and two of seven intents arithmetically unable to win. It splits into the layer, the basis it should score on, and what winning means. Change-Id: I9f6903ce999788747e0519ba9eeebf466e98f191
