Read together, Economy + Housing + Climate + Mobility + Green Access + Culture form one scoped view of Paris. Economic output and the modelled apartment market rent frame productive strength against housing cost pressure; they do not, by themselves, measure household affordability. Current conditions and nearby cool-green space connect immediate heat context with a potential cooling option, without claiming that proximity proves reduced exposure. Public-transport stop density and green-space proximity describe two forms of local reach, but a route-level connection still requires journey-time evidence.
