IP geolocation data
===================
server/data/geo.bin is a compact index built from the "IP to City Lite" database by DB-IP.com,
licensed under the Creative Commons Attribution 4.0 International license (CC BY 4.0):

Attribution (also shown on the dashboard): "IP location data by DB-IP.com"  https://db-ip.com

How it is used: when a visit arrives, its address is looked up in this file on your own server and only the
resulting place (country, state, town) is stored. The address itself is discarded. No outside service is contacted.

To rebuild the file with newer data:  npm run build-geo
