/*
 * Lightbox variant.
 *
 * The player fills the stage and the VIDEO does the fitting, via
 * object-fit: contain. That is the only arrangement here that works:
 *
 *   - The base .iv is a chat bubble (fixed 3/4 aspect, full parent width),
 *     so both of those must be cleared.
 *   - Sizing the wrapper to the clip does NOT work. `max-height: 100%` on the
 *     video resolves against a wrapper whose own height is auto, so it never
 *     applies; the video renders at intrinsic size and .iv's overflow:hidden
 *     crops it. That is a massively zoomed clip, not a fitted one.
 *
 * The background is transparent and the radius dropped so a full-stage box
 * leaves no visible slab — the clip reads as centred and letterbox-free,
 * matching how the <img> beside it presents.
