Does Polkadot have a max supply?

Hello there, I'm just wondering if you could help me understand something about Polkadot. As I've been delving deeper into the world of cryptocurrencies, I've come across this project and it's really piqued my interest. One thing that's been bugging me is whether or not Polkadot has a maximum supply. I know that some cryptocurrencies have a fixed amount that can ever be mined or issued, while others don't. Could you please clarify this for me? It would really help me in my understanding of this fascinating space.
