 ### When to Bump Version
 
 Bump version for:

 - ✅ New features added to the fork
 - ✅ Bug fixes in fork-specific code
 - ✅ Adopted upstream PRs that add functionality
 - ✅ Any change you want consuming projects to pick up
 
 Do NOT bump for:
+
 - ❌ Documentation-only changes (README, FORK.md, etc.)
 - ❌ Internal tooling/CI changes
 - ❌ Commits that will be reverted
