/*
 * Click-to-play placeholder for YouTube embeds.
 *
 * A YouTube iframe pulls roughly a megabyte of player JavaScript on every page
 * view whether or not the visitor ever presses play. This renders a thumbnail
 * instead and swaps the real iframe in on click, so the player is only paid for
 * when it is wanted. See /js/yt-facade.js.
 *
 * The facade inherits whatever class the original iframe carried, so the sizing
 * rules of the surrounding page (Tailwind's aspect-video, songs.css, or
 * song-page.css) still apply. Everything below is scoped to .yt-facade and must
 * not assume a particular parent.
