Euro-Office/DocumentServer ? reverse-engineered prompt

Build me a self hosted office document server that I can run in Docker and open on port 8080.

I want it to feel like a simple online office suite where people can create, open, and edit documents through the browser, with support for common office file types and the usual fonts, dictionaries, and templates that make it usable right away. Please make it easy to start with a basic example setup, and include sensible defaults like a JWT secret and an optional sample mode for testing.

If there are separate parts for the editor, server, integrations, or packaging, wire them together so the whole thing works as one installable service. Keep it focused on a production ready self hosted setup, but also make sure there is a clear local development path and a way to run or test the main pieces individually. If you need current details from docs or dependencies, look them up online and follow the project’s build notes.
