+ * When the meeting time-timer has reached / passed the scheduled end, draw a
+ * red inset frame around the whole conference video area. Implemented via an
+ * `::after` pseudo-element so the frame paints on top of LargeVideo / the
+ * filmstrip (those children fill #videospace and would otherwise cover any
+ * shadow / border drawn on the parent itself). The pseudo-element is
+ * non-interactive so it doesn't intercept clicks.
