//! Shared byte-parsing helpers for the WASM ABI boundary.
//!
//! The WASM exports accept fixed-size scalars and public keys as raw byte slices for performance, and
//! variable-length values (hex strings, JSON blobs) as `&str`. These helpers centralise the conversion
//! and validation logic so the individual modules only deal with strongly-typed values.
