Enhance a native <dialog data-hl-modal>. Opening and closing are fully declarative through Invoker Commands: a button with command="show-modal" and commandfor opens it, and a command="close" button inside closes it, with no JavaScript. showModal() already provides the top layer, focus trap, background inert, and ::backdrop; this enhancer only labels the dialog, locks background scroll while open, and mirrors the native open/close into onOpenChange/hl:open-change and the returned imperative API.
