1. Overview
This document ports the original Sphere Packing in Lean TeX blueprint to Verso Blueprints and tracks the same mathematical narrative.
The project formalizes Maryna Viazovska's theorem that no packing of unit
balls in \mathbb{R}^8 has density greater than the E_8 lattice packing;
see Viazovska (2017). The global upper bound comes from the linear
programming method of Cohn and Elkies (2003), and the crucial input is an
explicit optimal auxiliary function built from modular forms.
Compared with the upstream TeX source, this Verso copy reorganizes the blueprint into linked nodes and groups so that the dependency graph and summary are rendered directly from the structured document.
