Clarifying Serie A regulations

I want to confirm that Serie A has a 'Lista A' of 25 players, with Under-22 players (born from January 1, 2003, for the 2024-25 season) not counting toward this. For 2023-24, the Under-22 limit considered players born in 2002. I think I should mention key details like transfer window dates, closing times (CET), and registration related to deposits. It's also vital to note that free agents can be signed outside the window but need to meet specific criteria for registration.
