Heat, mortality and who lives where it's hottest in Hessen, 2000–2025 (Hitzerisiko Hessen). Open data from DWD, Destatis, Zensus 2022 and Landsat; heat-related deaths checked against RKI's estimates; surface heat in its five cities mapped on the 100 m census grid. Hypotheses and data rules fixed in docs/DESIGN.md before anything was modelled.
