Writing tone analyzer

This is a word list, not a model. Every score traces to the exact matched words above it, which makes it inspectable and blind at the same time: sarcasm is missed, and negation is missed too, so "not happy" counts "happy". A dimension with fewer than 3 signals reports not enough evidence rather than a guess, and the target ranges are editorial starting points, not standards. The sentence splitter is naive about abbreviations: "Mr. Smith wrote." counts as two sentences.
