 ## Next Steps
+
 None required. The fix is complete. GitHub Actions will:
 1. Import the JSON to MySQL (ID will be auto-assigned)
 2. Generate all export formats (JSON, CSV, SQL, XML, YAML, MongoDB)
 3. Update all distribution files
 
 ## Notes
+
 - Entry inserted before Dhamar in the JSON array to maintain some logical ordering
 - The `id` field is intentionally omitted as per contribution guidelines
 - MySQL AUTO_INCREMENT will assign the ID during import
