 * One row of the self-service summary: the caller's own company observed over
 * one time window. Two rows are returned per request — "current" and the
 * equal-length "previous" span — so the KPI tiles can render a value and its
 * delta without a second call.
 *
 * There is no `scope` here: a company only ever sees itself, so the
 * customer/platform split that the administrative summary carries is absent.
