- /api/v1/championship/hub?year=2026&source=local returns 179/154/147

+# Verification with Sprint fix:
+#   go run ./scripts/seed-verify-actual.go   # seeds /tmp/boxbox-verify.db on host
+#   # or use compose volume mount:
+#   docker compose -f docker-compose.yml -f docker-compose.verify.yml up --build
+#
+# Next time: use this for screenshots so API + React UI are real.
