    # Join the shared external network to communicate with other services.
    # Note: When communicating between containers on this network, use the

    # Example: To reach the API, use 'http://cryptosharia-api:5173'

    # `npm run dev -- --host 0.0.0.0 --port 5173` Starts the SvelteKit dev server and makes it visible outside the container
