Duplicate headers, empty headers, unclosed quotes, and malformed rows produce specific errors. The first release keeps CSV values as strings rather than guessing number, boolean, or null types.

The CSV parser runs locally. Input rows, headers, and JSON output are not sent to a server, logged, or stored in localStorage.
