## Display Rules
- Show the ASCII output exactly as returned — do not reformat it
- The box-drawing characters are intentional, preserve them
- Add brief commentary only if there's a notable trend or budget concern
- If no data exists yet, tell the user that tracking starts automatically
- For branch reports, mention that branch tracking requires working in a git repo
