//! necosystems series node graph data model with port-typed nodes and edges.
//!
//! `NodeGraph<N, E>` provides a pure graph model for node editors. Edges are
//! validated against port existence, direction, and `type_tag`, and the
//! optional `json` feature enables `neco-json` based round-trip codec support.
