What is the max supply of beam?

Could you please clarify something for me? I've been trying to understand the concept of cryptocurrency supply, and Beam particularly interests me. Could you tell me, what exactly is the maximum supply of Beam? Is there a fixed limit to the number of Beam coins that can be mined or issued? Or does it have an inflationary model where the supply can potentially increase over time? I'm curious to know how this affects the potential value and scarcity of Beam in the long run. Thank you for your assistance in clarifying this matter for me.
