Major nouns, verbs, adjectives, and adverbs are capitalized, while minor prepositions and articles (a, an, the, and, but, for, in, on, at, to) remain lowercase.

Does Sentence case handle multiple paragraphs?

Yes, it detects sentence terminals (. ! ?) across multiple paragraphs and capitalizes the first letter of each subsequent sentence.

What is CONSTANT_CASE used for?

CONSTANT_CASE (e.g. MAX_BUFFER_SIZE) is standard in software engineering for configuration constants and environment variables.
