/**
 * @deprecated Superseded by the Summary Row feature in `src/summary/`.
 *
 * This class was never wired into the render pipeline — `compute` has no caller
 * — so the `ColumnDef.showSummary` / `summaryAggregation` / `summaryLabel`
 * properties it reads produced no visible output. Those properties are now
 * honoured by {@link import('../../summary/summary-model').SummaryModel}, which
 * derives a total row from them when `GridOptions.summary` supplies no explicit
 * rows.
 *
 * Retained only so the `SummaryEngine` / `SummaryRow` / `SummaryCellValue`
 * exports do not disappear from the public surface. Use `GridOptions.summary`
 * and the `GridApi` summary methods instead; this will be removed in the next
 * major version.
 *
 * @see {@link import('../../summary/summary-service').SummaryService}
