notes:
- Demand and carbon intensity are SERIES and measures inside the generation tables,
  not separate datasets -- which is why the three bulk files cover what the API exposes
  as six endpoints.
- is_derived marks Ember's own aggregate series (Total generation, Clean, Fossil,
  Renewables, Demand, ...). Summing across `series` without filtering it double-counts.
- entity_kind separates countries from Ember's 15 precomputed aggregates. The groups
  OVERLAP (EU is a subset of OECD), so summing across entity_id without filtering
  double-counts differently.
- AU and MENA have no membership column upstream and cannot be derived from country
  rows; they are readable only as the aggregate rows Ember ships.
