Overview

Package geo resolves a client IP to an ISO 3166-1 alpha-2 country code using a pure-Go, embedded database (no external service, no file to mount). It is privacy-preserving by construction: callers resolve the country at request time and immediately discard the IP — GateCHA never stores or logs the raw address, only the aggregated country.
