//! Core types, traits, and error handling for the iab-specs ecosystem.
//!
//! This crate provides the shared foundation used by all `iab-specs-*` sub-crates:
//! - [`Extension`] trait for type-safe extension fields
//! - [`DefaultExt`] type alias (`Vec<u8>`) for opaque byte extensions
//! - [`Error`] and [`Result`] types for error handling
//! - [`slice_up_to!`] macro for safe string slicing
