The demo used the corpus I-beam, which is extruded along z and so stood upright. A new corpus part, cantilever-i-beam, is the same section on the YZ plane extruded along x, web upright: a sweep along a horizontal axis for the meshers, and a cantilever that bends downward on screen. The i-beam part is unchanged (its corpus row and the meshing tests keep it). The demo clamps it at x = 0 and loads the free end with 1000 N in -z through a kinematic coupling, and now checks the solution against beam theory and stops when it is off: tip deflection (bending plus shear) within 3 %, root bending stress (stress_xx along the top flange, extrapolated to the root, nodes from the Abaqus deck) within 2 %. docs/meshing/corpus.md regenerated with the new part.
