| # Purely informational -- config.py's PORT reads the platform's own PORT | |
| # environment variable at runtime (falling back to 7860 only when it's | |
| # unset) and that's the port actually bound, regardless of this EXPOSE | |
| # value. Render assigns and injects PORT itself (see render.yaml / | |
| # README.md "Deploying to Render"), so nothing needs to change here to | |
| # match it; 7860 is the default for a local `docker run` with no PORT set, | |
| # and for Hugging Face Docker Spaces, which expects 7860 specifically. | |
