/* Resource posts, premium layout (single-resource.php, ues-resource-premium.php). Loads on single
   resources only, after ues.css. From premium.css of UES_Blog_Premium_Mockup.html (mail 008) without
   the mockup chrome; the hero is the live photo hero (.hero.has-bg, ues_hero_bg) set to the mockup's
   proportions. html.rjs is set by the template before the article and kept by resource.js (rjs-ok):
   the reveal and the hidden steps apply only while the script runs, so every piece reads without it.
   Source of truth: ues-homepage git repo on Manny's machine. v1.2: a five-step drawn line (.tl.five). v1.3: the reviewer placeholder style is gone (mail 025). v1.4: so are the new copy outline and the photo slot (mail 029). */
