If there's such a thing as a universal character limit for alt-text in the Fediverse, it's not Mastodon's 1,500 characters.

It's Misskey's 512 characters.

That's also because Misskey has a bug that deletes alt-texts from outside if they're longer than 512 characters. So no matter how much work you've put into your long alt-text, Misskey users will think you haven't written any alt-text.
