You can't tell what this produces from a description, and the obvious
way to show it — screenshot a real run — would put someone's actual
repo names in a public README.
So the sample is generated: assets/make-sample.mjs builds a throwaway
HOME of invented repos, invented files and invented sessions, and the
real miner runs against that. The picture is what the tool genuinely
produces, from data that never existed. Checked the output and the
generator for anything real; the PNG carries no metadata chunks.
Keeping the generator next to the asset so the next person can
regenerate it rather than hand-editing a screenshot.
No-Verification-Needed: docs asset + dev-only generator, no plugin runtime surface
