var previewCornerRadius: CGFloat = 12
/// The corner radius of the preview image
var previewImageCornerRadius: CGFloat = 3
/// The side length of the preview image

/// The padding around the preview
var previewPadding: CGFloat = 12
/// The number of lines to preview
var previewNumberOfLines: Int = 5
/// The preview color for URL activity items
