REGIME III // STATE PREPARATION: UNCOLLAPSED 4-BLADE (det G = 0.892)
All 4 basis vectors span a non-degenerate 4-simplex around P(x₀, t₀). The 6 off-diagonal bivector faces C(4,2)=6 refract the 7 Argon-ion laser lines across D₄ umbilic & A₃ swallowtail caustics. Drag canvas to rotate in 4D (xw, yw, zw).
