Dockerfile

# Blog Post Generator — HF Docker Space
# One container, two isolated virtualenvs:
#   /opt/searxng-venv  → SearXNG (internal metasearch on 127.0.0.1:8080)
#   /opt/appenv        → the Gradio app (public on 7860)
# Keeping them separate avoids dependency conflicts between SearXNG and Gradio.
