🏆 Community Contributors

🥇 @jvantuyl - PR #16 fixing outline action dereferencing! Uncovered a subtle PDF spec detail (Section 9.4.1) - some PDFs embed actions directly while others use indirect references. Your comprehensive tests ensure this won't regress. 🔍✨

🙏 @mert-kurttutan - Thanks for honest feedback on README clutter (Issue #15). Your perspective as a new user helped us realize we were overwhelming people. The resulting documentation cleanup makes PDFOxide more approachable. 📚

✅ Verification

• All library and integration tests pass
• Format checks and clippy pass
