How do you build your planets?

Hi everyone.

I've been enjoying the change to how planet districts and buildings work. I'm not sure quite how to optimise my planets however.

I wondered if anyone had crunched the numbers or worked out any rules of thumb, and wanted to share how they would build a few example worlds and why:

• basic resource world
• research world
• alloy forge world Etc

Do you always have one of each basic resource district on worlds that produce secondary products for the build slots/extra jobs?

Do you use things like mineral support districts on basic resource worlds or are these not worth it under certain conditions due to trade upkeep?

Are dedicated trade worlds now essential or can you make enough spread across spare building slots?

Is it now best to have basic and secondary products made on the same planet or still better to specialise fully? Etc etc

Thanks in advance for sharing your thoughts, looking forward to reading them!
