Deft — a native UI framework for the D programming language.
Deft wraps native platform controls (Win32 today; GTK4 and Cocoa later) and provides a delegate-based event system together with an automatic layout engine. This module is the public entry point: import deft to pull in the core types.
Public re-exports are added here as each subsystem lands.
