German Readability Score

Scores how readable a German text is: Flesch Reading Ease (Amstad adaptation) plus the four Wiener Sachtextformel variants. Returns both scores, the underlying counts (sentences, words, syllables, sentence length) and the formulas, so the result can be recomputed. Syllable counting is a disclosed approximation (vowel-group heuristic), not an official certification.
