1//! # Shader Graph System
2//!
3//! A node-based shader graph system for the Proof Engine. Provides a visual-programming
4//! style interface for constructing GPU shaders from interconnected nodes.
5//!
6//! ## Architecture
7//!
8//! - **Nodes**: 40+ node types covering sources, transforms, math, effects, color, noise, and outputs
9//! - **Compiler**: Topological sort, dead-node elimination, constant folding, CSE, GLSL codegen
10//! - **Optimizer**: Type inference, algebraic simplification, node merging, variant caching
11//! - **Presets**: 15+ ready-made shader graphs for common game effects
12//! - **Serialize**: Custom text format for saving/loading graphs with round-trip fidelity
