    CenteredScrollTopMeasurements

    The measurements centeredScrollTop needs, all in CSS pixels.

    Plain numbers rather than DOM nodes on purpose: jsdom reports 0 for every layout box, so geometry expressed against live elements cannot be unit tested. The caller does the measuring; this module does the arithmetic.

    type CenteredScrollTopMeasurements = {
        rowOffsetTop: number;
        rowHeight: number;
        regionHeight: number;
        maxScrollTop: number;
    }
