widgets library

Stable high-level widget API for composable terminal UIs.

This library re-exports the stabilized widget surface from package:artisanal_widgets/widgets.dart.

Prefer the direct artisanal_widgets package when widget APIs are the main thing your app depends on. Use this umbrella entrypoint when you already want the broader Artisanal toolkit from a single package dependency.
