star-history-chart
Add a self-hosted "Stargazers over time" chart to any GitHub repo's README. GitHub now restricts the stargazers endpoint to a repo's own admins/collaborators, so third-party live services (star-history free tier, starchart.cc) return "Requires authentication" for everyone. This generates a static, theme-aware SVG in-repo and auto-refreshes it weekly with a GitHub Action using the repo's own GITHUB_TOKEN. Use when the star chart in a README is broken, shows "Requires authentication", or you want a star history that never breaks.
