Struct CartesianAzimuth 

pub struct CartesianAzimuth;

Cartesian azimuth: atan2(dx, dy), in radians, measured clockwise from the positive y-axis (i.e. 0 points along +y (“North”), π/2 along +x (“East”)).

Mirrors boost::geometry::strategy::azimuth::cartesian from boost/geometry/strategies/cartesian/azimuth.hpp:74-76, whose comment is explicit: “azimuth 0 is at Y axis, increasing right — as in spherical/geographic where 0 is at North axis”. This keeps the Cartesian bearing convention consistent with the crate’s spherical and geographic azimuths, which also measure clockwise from North.
