//! Geolocation Mocking (Feature 16)
//!
//! Mock GPS coordinates and location data for testing location-based features.
//!
//! ## EXTREME TDD: Tests written FIRST per spec
//!
//! ## Toyota Way Application:
//! - **Poka-Yoke**: Type-safe coordinates prevent invalid lat/long values
//! - **Muda**: Efficient location simulation without real GPS overhead
