• Ensure that the constant 'VisibleBlankRunes' includes all intended whitespace characters compared to 'BlankRunes'. If this change affects the trimming behavior, consider updating the related documentation for clarity.

• Using json.Marshal returns a JSON-encoded string (including surrounding quotes). Verify that this output format meets downstream expectations; if not, consider unquoting the result before writing.
