 * started and moved what the reader was looking at. Second, these

 * portrait (540x960) alongside the landscape ones (960x540). An aspect
 * box sized for either wastes most of the panel on the other — a 16:9 box
 * shrinks a portrait session to a sliver.
 *
 * So: a fixed height in vh, and object-fit: contain. Both orientations
 * fill it as well as they can, nothing resizes on play, and the box is
 * tall enough that a portrait recording is actually watchable.
