What are emblems and how do they differ from permanents in the game of Magic: The Gathering?

Emblems are unique effects in Magic: The Gathering that are created by certain cards and cannot be interacted with or removed by normal means. They represent a lasting impact on the game. Permanents, on the other hand, are cards that stay on the battlefield and can be interacted with by players through various spells and abilities. Emblems are not considered permanents and exist separately from the game's normal rules for permanents.
