//! Shared utilities.
//!
//! The framework-agnostic helpers (`FourCharCode`, `ffi_string_*`, completion
//! handlers, panic-safe wrappers) now live in `apple_cf::utils` and are
//! re-exported here for backward compatibility.
//!
//! `error.rs` is intentionally NOT migrated — it carries SCStream-specific
//! error variants that don't belong in the framework-agnostic foundation.
