//! Scheme hashing: domain operations (`ops`), ADRS address words (`address`),
//! the portable-vs-Solana `backend`, and the compile-time scheme-hash `suite`.
//!
//! This is the Rust analogue of Solidity's shared scheme-hash support layer.
//! Primitive components (`uxmss`, `fors_c`, `hypertree`) build on these
//! helpers, while higher-level core and signer modules import the subset they
//! need. EVM-domain hashes such as canonical action-message construction and
//! public-key commitments stay on keccak under every suite and are therefore
//! owned outside this module.
