Carlox1/6b6t-webmap ? reverse-engineered prompt

Build me a Java mod for the 6b6t real time map that lets people collaborate on the map together in a simple way.

I want a clean interface where users can open the map, see it update live, and add or adjust map info without stepping on each other’s changes. It should feel like a shared map tool, not something complicated. If it helps, include a basic way to view current map data, make edits, and have those edits sync so everyone sees them quickly.

Please keep the design simple and practical, with the main focus on real time collaboration and a smooth map viewing experience. If you need to check current docs or best practices online, go ahead and do that.
