//! `Helpers/Extensions/*`: one module per Swift file. A Swift `extension X`
//! becomes an extension trait `XExt` implemented for the objc2 type (or free
//! functions for value types). Pure logic is in the platform independent
//! modules; the AppKit traits are `cfg(target_vendor = "apple")`.
//!
//! Unportable (SwiftUI only): `View+Extension.swift`, `Transferable+Extension.swift`.
//! `UUID+Extension` (CFUUID) lives in [`uuid`]; `KeyboardShortcut+Extension`
//! is `helpers::keyboard_shortcut`.

// Platform independent.
