 Parser tests cover standard and extended CAN IDs, whitespace, payload storage
 boundaries, missing fields, malformed and overflowing numbers, reserved ID bits,
 error paths and line numbers, and integration with signals and comments.
+Comment regressions cover tabs, escaped quotes/backslashes, multiline text with
+blank lines and indentation, CRLF, missing final newlines, comments preceding
+frame/signal definitions, last-wins and empty overwrites, normalized ID boundaries,
+standard/extended separation, malformed syntax/IDs, and missing targets. Errors
+verify both structured diagnostics and the throwing API at the starting line.
 Duplicate definitions are rejected at their source lines, including equivalent
 extended ID encodings and repeated signal names within a frame. Standard and
 extended frames may share a numeric ID, and separate frames may reuse signal names.
