--- 'stackedValue' kind — a primary number over an optional muted secondary (shown
--- only when it differs), rendered by the gadget's scwStackedValue type. The raw
--- current number is kept for sort + the number filter. Generalised from
--- PledgeVehicleGrid's buildPriceStack. Spec: { field, header, curLabel, origLabel?,
--- prefix? (default '$'), width? }.
