To test Pigment CSS demo apps, you can directly run -
pnpm nx run @app/vite-app:preview to start vite demo or pnpm nx run @app/next-app:preview to start nextjs demo after building automatically.
To start either of the apps in dev mode, just run -
pnpm nx run @app/vite-app:dev or pnpm nx run @app/next-app:dev
