    Each row below is a <code>Workbook</code> with a different <code>Culture</code>. The canonical
    <code>Cell.Formula</code> stays identical in every culture - only user-facing entry and display change.
    <code>Workbook.Culture</code> defaults to <code>CultureInfo.CurrentCulture</code>; set it explicitly in
    server-side code so results do not depend on the host locale.
