Set up Playwright component testing for a React application with @playwright/experimental-ct-react

Steps

1. Install the adapter: npm install --save-dev @playwright/experimental-ct-react and run npx playwright install to ensure browsers are present
2. Create a playwright/index.html entry point and a playwright/index.tsx (or .jsx) file that imports any global styles or providers needed by components
3. Write a test file importing mount from @playwright/experimental-ct-react, then call mount(<MyComponent />) inside a test to render the component in a real browser
4. Use Playwright locators (getByRole, getByText, etc.) against the mounted component and assert with expect; no DOM abstraction layer is needed
5. Run tests with npx playwright test --config=playwright-ct.config.ts; a separate config file pointing to the ct adapter is required alongside any existing e2e config
