# We will run 'vite' in development mode (or 'vite preview' for prod-like serving, 
# but Uvicorn user usually implies a simpler dev-like setup or just Python preference).
# Since user asked "Why not use Uvicorn for frontend", strictly speaking Uvicorn is Python server.
# Frontend (Vue) is JS. We cannot run Vue with Uvicorn directly.
# BUT, we can use Vite's preview or dev server.

# Expose Vite's default port
EXPOSE 5173
