# XWUIStockAlertWidget

An out-of-stock "notify me" widget. When `data.inStock` is true, renders a small in-stock confirmation line. When false, shows an out-of-stock banner, an email input, and a "Notify me" button; a basic client-side email shape check gates submission, and a successful submission flips to a confirmation message.
