 * Authenticated dashboard render — proves the seed user can reach the

 * errors.
 *
 * The dashboard self-gates each tile on (visible AND has data), so a
 * fresh seed user with zero measurements would render an empty strip
 * and skip all charts. Rather than seed measurements before this spec
 * runs (which couples the spec to a particular signature of the
 * `/api/measurements` shape), we mock `/api/analytics` and
 * `/api/dashboard/widgets` to return a deterministic dataset. The
 * widget layout + chart wrappers are pure enough that asserting on the
 * mocked-data render exercises the same code paths as a real session.
