//! Lund String Fragmentation Model
//!
//! This module implements the Lund string fragmentation model for QCD hadronization.
//! The model treats the color flux tube between a quark-antiquark pair as a
//! relativistic string with tension κ ≈ 1 GeV/fm.
//!
//! # Physical Model
//!
//! When a q-q̄ pair separates, the potential energy stored in the string
//! increases linearly with distance. When sufficient energy is available,
//! new q-q̄ pairs are created from the vacuum, breaking the string into
//! shorter segments that eventually form hadrons.
