## 🧱 **Purpose**

This directory is the stable reference area for compact, lookup-oriented documentation such as:

- port and endpoint mapping
- configuration reference notes
- operational lookup guides

## 🚀 **Next Steps**

- Use `PORT_MAPPING_GUIDE.md` as the first stop for networking or port questions.
- Add new reference docs here when they are lookup-oriented rather than narrative.
- Keep reference material synchronized with the master index.
