//! Lazarus Receipts SDK - Cryptographic receipt verification.
//!
//! This crate provides Merkle proof verification using the positional v1.0.1 rule,
//! which is the auditor-grade standard for Lazarus Receipts.
//!
//! # Example
//!
//! ```rust
//! use lazarus_receipts::{hash256, verify_merkle_proof_directional, ProofNode};
//!
//! let leaf_a = hash256(b"leaf_a");
//! let leaf_b = hash256(b"leaf_b");
//!
//! // Build root: H(leaf_a || leaf_b)
//! let mut combined = Vec::new();
//! combined.extend_from_slice(&leaf_a);
//! combined.extend_from_slice(&leaf_b);
//! let root = hash256(&combined);
//!
//! // Proof for leaf_a: sibling (leaf_b) is on RIGHT
//! let proof = vec![ProofNode { side: 'R', hash: leaf_b }];
//!
//! assert!(verify_merkle_proof_directional(leaf_a, root, &proof));
//! ```
