Phase 2a: NUTS-1 regional income for Germany (16 Bundesländer via admin1→NUTS-1 mapping)
Phase 2b: EU-wide NUTS-2 via GISCO spatial join + US Census ACS state income
- All EU-27+EFTA+UK locations now auto-resolve to NUTS-2 via ST_Contains
- Germany gets sub-Bundesland (38 Regierungsbezirke) differentiation
- US gets state-level income with PPS normalisation
- Income cascade: NUTS-2 → NUTS-1 → US state → country-level
