• Testing and validation

Testing and validation

• Add a colocated .test.tsx file for new components and changed behavior.
• Use Vitest and Testing Library to test behavior visible to users. Prefer accessible queries and user interactions over implementation details.
• Cover relevant loading, error, empty, and success states as well as important interactions.
• Do not test React, Chakra UI, React Router, or other third-party internals.
• Keep tests deterministic and restore mocks between tests.
• Before finishing a change, run pnpm lint, pnpm test, and pnpm build. Run pnpm format when source formatting changes.
