 * under test was started with, and every signed-in test would fail looking
 * like an authorisation bug. Pinning it here keeps both sides in agreement.
 *
 * The suite truncates every table, so an unset TEST_DATABASE_URL is a hard
 * stop rather than a fallback to whatever DATABASE_URL happens to point at.
