Meeting Overlap Math, Explained
How UTC offsets and working-hour windows produce the overlap grid.
Each selected zone is rendered as a column of local hours for the same instant. ClockMatrix computes every zone's offset from UTC with Intl and shifts the shared timeline, so the columns always line up on the same moment.
