Sentence case is a simple heuristic — it capitalizes after ".", "!", and "?" and does not recognize abbreviations like "Dr." or "U.S." camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE detect word boundaries in both plain phrases and pasted identifiers (e.g. "myVariableName"), and strip punctuation other than existing separators.
