Unlock: The Multivariate Normal Distribution

The multivariate Gaussian as the joint of d correlated random variables: density derivation from standard normals via affine maps, the completing-the-square recipe, Schur-complement marginals and conditionals, the MGF and characteristic function, and the algebraic identities that power every Bayesian Gaussian derivation downstream.
