Conversation
Copilot CLI runs shell commands with `NODE_ENV=production` in the environment, which leads to errors when validating its changes against the view tests, because the `React.act` function (used by `@testing-library/react` via `react-dom/test-utils`) is only exported when `NODE_ENV != production`.
