/**
 * Mock rows for the Exxat One hubs — two on the Sites side, two on the Schools
 * side.
 *
 * These four surfaces were `_product-shell-placeholder` scaffolds until now,
 * which meant Exxat One had no real screen anywhere in the app. Building them
 * on the standard `ListPageTemplate` + `HubTable` stack gives the products
 * something a coordinator can actually use, and gives the marketing pages under
 * `/home` honest screenshots instead of illustrations.
 *
 * Data is deliberately small and hand-written rather than generated: twelve
 * legible rows read better in a screenshot than a hundred synthetic ones, and
 * the totals across the four sets stay internally consistent (the same brands,
 * sites, and programs recur, so the products look like one system).
