A Closed-Form Master Solution for Gravitational Decoupling of a Unified Family of Isotropic Stellar Seeds

We present a unification scheme for anisotropic compact stars generated via minimal geometric deformation (MGD), built on a two-parameter seed family $ν(r)=\text{Ln}[C(1+ar^{2n})^{m}]$ whose radial metric potential $μ(r)=e^{-λ(r)}$ is fixed in closed form by the isotropy condition. At $n=1$ the fami
