How are word boundaries detected?

The tool splits on non-alphanumeric characters AND on lowercase→uppercase transitions, so `getUserByEmailAddress` and `get_user_by_email_address` both produce the same word list.

Are acronyms preserved?

Runs of uppercase letters are treated as a single word until the last uppercase before a lowercase (so `parseHTMLString` splits as `parse` / `HTML` / `String`).

Which case should I use?

camelCase for JS/TS variables, PascalCase for classes and React components, snake_case for Python/Ruby/DB columns, kebab-case for URLs and CSS classes, CONSTANT_CASE for env vars.
