unacms/UNA ? reverse-engineered prompt

Build me the UNA community management system so I can run an independent social site on my own server.

I want a working web app with the main community basics in place, like member accounts, profiles, posting and browsing content, search, messaging or chat, notifications, and a simple admin area to manage the site. It should also be ready for community features like content management, collaboration, and some built in commerce or learning style sections if the platform already supports them.

Please make it easy to install locally with the existing setup, and make sure the app runs cleanly in Docker with the database and supporting services. If anything needs current setup or dependency info, look up the latest docs online and follow the project’s recommended install flow.

I care most that the site feels usable right away, looks polished, and that the core community experience works end to end without obvious broken pages.
