Nitinol Stent Flat-Pattern Deployment (2D)

This is the 2D counterpart to the 3D Nitinol stent deployment model: instead of a rendered tube, it shows the stent's own laser-cut flat pattern unrolled — the diamond-cell mesh exactly as it exists before being rolled and welded into a cylinder. Retracting the sheath opens each diamond hinge according to the same idealized superelastic stress-strain law that governs the 3D model (identical constants: austenite-finish temperature, loading/unloading plateau stresses, elastic and lock-up moduli), so the physics is byte-for-byte the same — only the representation changes, from a rendered cylinder to a technical flat-pattern diagram with a live hysteresis-loop readout.
