The repo's first frontend test setup: Vitest, React Testing Library, jsdom. Scoped to the flows that lose money or leak data when broken, per spec 4. lib/api.ts collapses every failure into three the UI can act on: NotConnected (unreachable, or no URL baked in), ApiError 401 (redirect), and ApiError with the backend's own message, which is customer-facing and shown verbatim rather than replaced with something vaguer. The not-connected panel names the variable, the value baked in, and both reasons it fails -- unreachable from the browser, or missing from admin's ADMIN_ORIGIN. Proven by test before it existed.
