Use this when you need exact word, character, sentence, and paragraph counts instead of estimating.

Use this when you need exact word, character, sentence, and paragraph counts instead of estimating. Deterministic: same input, same output. Uses Unicode-aware segmentation (Intl.Segmenter): characters are grapheme clusters, so an emoji or an accented letter counts as one; words are word-like segments; sentence splitting is abbreviation-aware (Dr., etc., won't end a sentence). charactersNoSpaces counts graphemes after stripping whitespace, and paragraphs are blocks separated by blank lines. Example: "Café 👩‍💻!" -> words 1, characters 7, charactersNoSpaces 6, sentences 1, paragraphs 1. Empty input returns all zeros.
