+{{/* 
+    GetFeaturedImage
+
+    This partial gets the url for featured image for a given page. 
+    
+    If a featured_image was set in the page's front matter, then that will be used.
+
+    If not set, this will search page resources to find an image that contains the word
+    "cover", and if found, returns the path to that resource.
+
+    If no featured_image was set, and there's no "cover" image in page resources, then
+    this partial returns an empty string (which evaluates to false).
+
+    @return Permalink to featured image, or an empty string if not found.
