Principal component analysis of spectral fluctuations in heavy-ion collisions yields thermal and geometric normal modes that explain 99.5% of variance and account for measured flow observables v0(pT) and v02(pT).

The equilibrated core in O+O collisions overtakes the nonequilibrium corona above midrapidity multiplicity of about 20, yet corona contributions persist in central events, making pure hydrodynamics inadequate.
AMPT simulations show the ratio of nonlinear response coefficients between U+U and Au+Au collisions remains stable across evolution stages, isolating initial geometric correlations.
