sulu/sulu ? reverse-engineered prompt

Build me the core of a PHP content management system like Sulu, using Symfony, with a clean admin area for managing pages and content.

I want it to support multiple languages and multiple websites or portals, with an intuitive backend where editors can create, edit, publish, and organize content. Please include a basic content lifecycle, login protected admin screens, and a simple public site that can render editable pages from stored content. Make it feel like a real CMS foundation, not just a demo, and keep it modular so it could be extended later with more features.

Use modern PHP 8.2 compatible code, set things up so it runs well in a typical Symfony app, and make sure the project structure feels like something a team could build on. If you need to check current Symfony or PHP docs online, do that. Focus on getting a solid working baseline in place with sensible defaults, clean UI, and a straightforward developer experience.
