/**
 * Pickipedia — Show: page hero.
 *
 * For mainspace pages whose title starts with "Show:" (the legacy
 * mainspace convention used pre-namespace), adds .pickipedia-show
 * to body and absorbs Template:Show's infobox into a poster-style
 * hero. If the page does not use Template:Show only the body class
 * is added — the setlist typography in Common.css still applies.
