+## Structural context (World Bank)
+
+Beyond the divergence data, this dataset ships `data/colombia-structural-context.csv`: official, open World Bank indicators that frame the country — **governance** (Worldwide Governance Indicators, 0-100 scale) plus **economy & education** (World Development Indicators: population, GDP, GDP per capita, inflation, public education spending, expected years of schooling). These are annual structural indicators that contextualize the country; they do **not** predict the electoral outcome. Columns are documented in `DATA_DICTIONARY.md`.
