/*
 * Xbox WebView2 renders the <video> element via the OS MediaFoundation
 * compositor, which on this platform does not upscale an intrinsic-smaller
 * frame to the CSS box size (it effectively treats object-fit: contain like
 * scale-down). The Media Engine intentionally starts playback at a
 * low-resolution representation on Xbox for fast startup, which makes this
 * visible as a "video starts small, grows to full over a few seconds" scale
 * animation.
 *
 * Adding transform: translateZ(0) on the <video> forces Chromium to composite
 * it itself (bypassing the OS overlay that ignores CSS sizing) so CSS layout
 * and object-fit are respected during ABR ramp-up. That transform creates a
 * new stacking context and would paint the video above the Lightning canvas
 * by default, so we pin both layers explicitly with z-index to keep the
 * canvas (player UI, hole-punch) on top.
