+## Batch 7 Priority
+
+Status: complete. Visual contact sheets, image dimensions, unit base/action pairs,
+`pnpm build`, and `pnpm verify:flow` passed.
+
+This batch keeps pressure on the highest-repeat story backgrounds, adds campaign
+variants for mid-campaign supporting officers, and moves the unit design count
+toward the 100+ complete-pair target.
