TB Contact Tracing Investigation Simulator (3D)

A genuine WebGL/Three.js companion to the 2D contact-tracing simulator: the same concentric-circle ("stone in the pond") exposure model, the same secondary-LTBI-rate, needs-evaluation and new-active-case math, rendered as real concentric 3D exposure shells around the index case instead of a flat 2D ring diagram.
