Why is it incorrect to capitalize the seasons?

[Sorrowful Maiden]

i want to know why it is incorrect to capitalize the seasons. i mean what it
wrong with it? isn't capitalization of a word a way to let people know that
the word is being stressed? can someone please let me know what they think of
it?

Capitalization is not for stressing a word or showing its importance. If you
want to emphasize a word, it's appropriate to use italics or, online, the *
symbol before and after.

Capitalization is for proper nouns, titles and the beginning of sentences.
