Parallel-Spring Stress-Shielding Diagram: Lattice Implant

This is the 2D-native counterpart to the 3D graded-porosity lattice implant simulator: instead of an instanced strut mesh rendered in perspective, it draws the three diagrams an implant engineer would actually reach for. A 2D unit-cell truss elevation shows the lattice's bending- vs. stretch-dominated bracing and physically compresses by a real spring displacement; a parallel-spring circuit diagram makes the equal-displacement load-sharing between implant and bone explicit, with force arrows that always sum to the applied load; and a suitability curve plots osseointegration score continuously against pore size instead of a single readout. Tune porosity, topology, pore size and load and watch all three respond together, computed from the same Gibson-Ashby cellular-solids law as the 3D version.
