The selected pack release is keo optimized Fabric 26.3.zip. That file is for Minecraft 26.3 with Fabric 0.19.5. It contains 23 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
