/**
 * @file Regression test for the lane card's status badge. Every lane status
 * the server can set must have a real translated word behind
 * `t("status." + lane.status)`; before this test existed, no locale defined
 * any `status.*` key, and i18next's default missing-key behavior (return the
 * key itself) hid that from the `||` fallback, so the badge showed literal
 * text like `status.active`.
