  The drawer slides in from the right when opened. It displays cart items
  and checkout options.

  ## Attributes

  * `cart_items` - List of cart items to display. Each item should have
    `image`, `name`, `variant`, and `price` keys. Default: []
  * `subtotal` - The subtotal to display. Default: nil (shows "£0.00")
  * `mode` - Either `:live` (default) for real stores or `:preview` for theme editor.
    In preview mode, "View basket" navigates via LiveView JS commands.
