//!
//! Provides algorithms for robot localisation and mapping:
//!
//! - [`dead_reckoning`] — wheel odometry + IMU complementary-filter fusion.
//! - [`ekf_slam_2d`] — 2D Extended Kalman Filter SLAM (range–bearing landmarks).
//! - [`pose_graph`] — linear pose-graph optimisation with loop-closure.
