What is the max supply of drift protocol?

Could you please clarify for me the maximum supply of the Drift Protocol? I'm interested in understanding the total number of tokens that will ever be in circulation, as this can have a significant impact on the value and scarcity of the asset. Is there a specific cap on the total supply, or is it subject to change over time? Additionally, how does the protocol manage the distribution of these tokens, and what measures are in place to ensure a fair and equitable distribution among participants?
