1//! Core value types for Shape
2//!
3//! This crate contains the foundational value types and core data structures
4//! used throughout the Shape language implementation. The canonical runtime
5//! representation is `ValueWord` — an 8-byte NaN-boxed value.
6//!
7//! Dependency hierarchy:
8//! - shape-value → shape-ast (no circular dependencies)
9//! - shape-runtime → shape-value (for types)
10//! - shape-vm → shape-value (for types)
