+standing at the edge of the district keeps all nine of its spots, or the card would be unplayable
+exactly where the district ends. And it may **never stand in the Running Track's row**, which inside
+the Limits is always full anyway — beyond the sign that row is the ground the main grows onto, and a
+Modifier parked there would block the Limits sign from moving outward (§2.1).
