/**
 * R8UXB-008 — Dual hub source-of-truth drift guard.
 *
 * ContentHub.tsx and RecoverHub.tsx both render Content cells. This test
 * asserts that both files import from content-hub-cells.ts (the shared
 * module) so there is exactly ONE authoritative cell definition.
 *
 * Future drift: if a dev adds a Content cell directly in ContentHub.tsx or
 * RecoverHub.tsx instead of updating content-hub-cells.ts, this test fails CI.
 *
 * Also asserts that the ContentHub route now redirects to the Recover hub
 * server-side (R8UXB-008 preferred resolution).
