Major rivers

Curated simplified major-rivers subset served as a static app-hosted GeoJSON (public/geo/major-rivers.geojson) - zero server, cost-lean path 2. A coarse cartographic overlay of the world's principal rivers, not a precise hydrological product. Off by default, opt-in. Full HydroRIVERS network + HydroATLAS attributes are DEFER (download-only, no free hosted tiles without a tiler). Swap MAJOR_RIVERS_URL to a fuller simplified export to upgrade.
