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

// Re-export core types
