// A modular staircase: full 48 wide on x (x 0..47), 48 deep on y. Six solid steps, each 8 deep on y and 4 taller than the previous, rising from z 0..3 at the front (y 0..7) to z 0..23 at the back (y 40..47), filled solid underneath. Light grey stone treads with a lighter front edge on each step, darker stone risers, flat vertical sides.
