file.sample rubber-seal: a gasket ring of hybrid hex8 elements in four
mapped quarter blocks, squeezed 2.5 mm between plates bonded to it
(nonlinear static, Mooney-Rivlin rubber). Its test frees the plates and
matches the closed form for incompressible uniaxial compression within 3 %,
and bounds the bonded ring's extra stiffness. The plates are prescribed
displacements until implicit contact (#161) can press it into a groove.

file.sample drop-test: an L-bracket standing on its foot (a SolidCraft script
in sample.rs) swept into hex8, falling 2 m onto a rigid floor tilted 15 deg;
explicit dynamics for 1 ms with gravity and plasticity. Its test checks the
mass against rho V, the impact speed sqrt(2 g h) and kinetic energy, the
energy balance and the momentum the floor takes. docs/examples.md starts
with it, and its picture is docs/media/examples/drop-test.png.
