/*
 * EP YouTube — frontend styles
 *
 * The .youtube box is a fixed-aspect placeholder that holds either a thumbnail
 * (initial state) or an iframe (after click). Default aspect is 16:9 via the
 * padding-top hack; the shortcode overrides padding-top inline for other ratios.
 *
 * Why the padding-top hack and not aspect-ratio: the hack works in every
 * browser back to 2010 and is what Chris's original ships. aspect-ratio is
 * fine in modern browsers but PM sites support old Safari that doesn't grok it.

   When the box is 16:9 and we're using YouTube's sd thumbnail, the image
