Manual testing

Here's how I tested:

Created a new sandbox of type react-native-web/vite-expo-ts in dev --no-link mode
After the sandbox is created, and while dev is still running, in a separate terminal

cd sandbox/react-native-web-vite-expo-ts
npx storybok add @storybook/experimental-addon-test
yarn vitest

The tests don't all pass, but many of them do.
