Light and dark variants, alt text, and one provenance line. Provenance is text in your README, never baked into the image URL, so the chart stays cacheable.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
