Is core a DeFi?

Could you please clarify for me, is Core considered a part of DeFi, or does it fall outside that category? I've been trying to understand the landscape of decentralized finance, and I'm not entirely sure where Core fits in. If it is indeed a DeFi project, could you explain what features or functionalities it offers that are typical of DeFi applications? And if it's not, could you provide some insight into why it's not classified as such? Thank you for your help in clarifying this for me.
