## Product summary
LOCUS is a static web application that:
1. Accepts free-form address text (or device geolocation)
2. Geocodes via public providers (ArcGIS World Geocoder, US Census, Photon, Nominatim)
3. Returns country, state/region, county, city/locality, postal code, feature type, source, lat/lon
4. Shows the point on an interactive MapLibre + OpenFreeMap basemap
5. Optionally saves places to browser localStorage and visualizes them on a 3D globe (globe.gl)

## What LOCUS is not
- Not a paid SaaS geocoding API for third-party backends
- Not a navigation or turn-by-turn routing app
- Does not store user locations on a server; saves are local to the browser
- Does not require login
