/**
 * Playwright config for Africa Alert E2E tests.
 *
 * Assumes both servers are already running:
 *   - Server  on http://localhost:3001  (`cd server && npm run dev`)
 *   - Client  on http://localhost:3000  (`cd client && npm run dev`)
 *
 * The client Vite dev server proxies `/api/*` to :3001, so all tests
 * can navigate to `http://localhost:3000` and the auth/contacts/etc.
 * calls still hit the API on 3001.
 *
 * To run the server + client first:
 *   cd server && npm run dev      # in one terminal
 *   cd client && npm run dev      # in another terminal
 * Then in a third terminal:
 *   cd client && npm run test:e2e
