# Set the environment variable for the Next.js port (default is 3000)
# Hugging Face Spaces typically exposes port 7860 for Gradio/Streamlit/etc,
# but for general web apps (like Next.js via the static host option or if you set up a custom server),
# it might expose port 3000 by default when detecting a standard Next.js app.
# It's good practice to set this, but Spaces often handles port mapping.
