mdziekon/UniEngine ? reverse-engineered prompt

Build me a browser based space strategy game engine like OGame, where players can register, log in, manage their empire, build structures, research tech, send fleets, attack other players, chat, join alliances, and view stats and battle reports.

I want the whole thing to feel like a playable game server, with the main pages and flows already in place, plus an install wizard so I can set up the database and admin account easily on a normal PHP and MySQL host. Please include the common game screens like overview, galaxy, fleet movement, buildings, technology tree, messages, profile, alliance, shop, and combat related tools and reports.

Make it work cleanly in the browser, keep the design simple but usable, and make sure the project can run locally and in Docker too. If you need current setup details or best practices, look them up online before you finish.
