- Headings, tables and code fences are kept with their content instead of being cut in half.
- Overlap carries the tail sentences of one chunk into the next, which is what keeps a definition and its exception clause retrievable together.
- The chunk size and overlap here are the real engine defaults (700 characters, 15%), not a mock.
- Nothing is uploaded, and no model is needed for this tool.
