//! Implementation of #[derive(HexValueItem)] macro.
//!
//! Automatically implements the HexValueItem trait with a default validation
//! that returns Ok(()). Override the validate method in your impl block if
//! custom validation logic is needed.
//!
//! Revision History
//! - 2026-07-20T00:00:00Z @AI: Fully-qualify generated paths (::hexser::, ::std::) for hygiene.
//! - 2025-10-09T11:03:00Z @AI: Initial HexValueItem derive implementation.

/// Derive HexValueItem for a type
