+// lazy-loading.js doesn't; while that file's written with the same kinda
+// modern syntax/APIs used all over the site, displaying the images is a pretty
+// damn important thing to do, so we have this goodol' Olde JavaScripte fix for
+// 8rowsers which have JS ena8led (and so won't display gener8ted <noscript>
+// tags) 8ut don't support what we use for lazy loading.
