Editor/Geometry/ArchStairAxes.cs
A small readonly struct used by the Editor to represent stair axes in 2D/3D. It stores an origin and yaw, computes a forward (Along) vector from yaw, provides an Across perpendicular, and helper methods to get flat 2D points, 3D points and a rectangular loop of 2D corners.
