 *
 * The one thing that works reliably across BOTH classic-table and
 * modern-grid cart themes: ask the td to span every grid column
 * via `grid-column: 1 / -1`. For classic tables this is ignored
 * (grid properties don't apply), and colspan still carries the
 * day. No need to force `display: table-row` on the <tr> — that

 * to stop applying to the following rows, making voucher / box
