TXT Sample File for Whitespace and Long Line Validation
Exercise whitespace-sensitive parsing, outline rendering, long-line handling, and large-text previews with real TXT fixtures instead of synthetic padding.

Validation Checklist
- Check whether tabs, mixed indentation, and trailing whitespace affect parser output or rendering.
- Validate preview truncation, line wrapping, and search behavior on long-line text fixtures.
- Compare small structured TXT controls against 1MB to 5MB plain-text files before promoting text-processing changes.
