+> [!IMPORTANT]  
+> ⚠️ **Project Status: End of Maintenance**
+>
+> As of **January 2026**, this project is no longer actively maintained.
+>
+> I previously announced a search for a new maintainer, but unfortunately no one has stepped forward
+> to take over the project. Due to personal time constraints, I am no longer able to continue development or provide support.
+>
+> **What this means:**
+> - ❌ No further feature development
+> - ❌ No bug fixes or updates
+> - ❌ No guaranteed support
+>
+> The repository will remain available for reference and forking.
+>
+> 💡 I would be very happy to see this project continued by the community.  
+> If you plan to fork it and continue development: **may the best fork prevail.**
+>
+> Thank you to everyone who used, tested, and contributed to this project ❤️
