+ * A Trait common for optional Media Entity and Video Embed Media integration.
+ *
+ * The basic idea is to display videos along with images even within core Image,
+ * and to re-associate VEF/ME video thumbnails beyond their own entity display.
+ * For editors, use Slick Browser, or Blazy Views field.
+ * For client-side, Blazy Views field, BlazyFileFormatter, SlickFileFormatter.
+ * Why bother? This addresses a mix of images/videos beyond field formatters
+ * or when ME and VEM integration is optional.
+ *
+ * For more robust VEM/ME integration, use Slick Media instead.
+ *
