function tameVideos() {
document.querySelectorAll('video').forEach(function (v) {
if (v.dataset.jzTamed) { return; }
v.dataset.jzTamed = '1';
v.muted = true;
v.autoplay = false;
if (!v.paused) { v.pause(); }
v.addEventListener('play', function () {
if (!v.dataset.jzUserPlay) { v.pause(); }
});
v.addEventListener('click', function () { v.dataset.jzUserPlay = '1'; });
});
