document.addEventListener('DOMContentLoaded', function () {
	// Bail if the notice data is not available.

	// Bail if no warnings are found.

	// Build the notice.
	// Gutenberg's Notice component renders `message` as plain text with
	// `white-space: normal`, so `\n` collapses to a space and any leading
	// `- ` dashes look odd. Inline the items with `; ` separators instead —
	// this reads naturally on the single line the component actually renders.
	const message =
		convertkit_legacy_resource_notice.intro +
		' ' +
		convertkit_legacy_resource_notice.warnings.join('; ');

	// Create the notice.
	wp.data.dispatch('core/notices').createWarningNotice(message, {
		id: convertkit_legacy_resource_notice.id,
		isDismissible: false,
	});
});
