/**
 * Shared UI component declarations for plugin frontends.
 *
 * These components are exported from `@paperclipai/plugin-sdk/ui` and are
 * provided by the host at runtime.  They match the host's design tokens and
 * visual language, reducing the boilerplate needed to build consistent plugin UIs.
 *
 * **Plugins are not required to use these components.**  They exist to reduce
 * boilerplate and keep visual consistency. A plugin may render entirely custom
 * UI using any React component library.
 *
 * Component implementations are provided by the host — plugin bundles contain
 * only the type declarations; the runtime implementations are injected via the
 * host module registry.
