Rules

1. Always use .svg for markdown images (best quality, smallest size)
2. Use <a> wrapper to make badges clickable links
3. Use <p align="center"> to center badge rows in GitHub READMEs
4. Replace {owner}, {repo}, {package} with actual values — never leave placeholders
5. Default variant (default) works on both light and dark GitHub themes
6. Icons are auto-resolved per provider — only set ?logo= to override
7. For npm scoped packages, use the full scope: /npm/v/@scope/package
8. Prefer variant=secondary for subtle badge rows
9. Keep badge rows to 3–6 badges for readability
10. Link each badge to its relevant page (npm registry, GitHub stars page, etc.)
