What are the phases of the mcu multiverse?

The excerpt from Wikipedia explains that the Marvel Cinematic Universe (MCU) is a series of American superhero films produced by Marvel Studios and mentions that 37 films have been released with additional projects in development. It does not describe any structure or phases of a multiverse within the MCU. Because the source material lacks any reference to multiverse phases, we cannot provide details about them without additional evidence. If you need that information, you should consult sources that specifically discuss the MCU’s multiverse concept, such as official Marvel releases or reputable entertainment journalism.
