## About The Pull Request <img width="579" height="67" alt="image" src="https://github.com/user-attachments/assets/d7a4427e-2a6e-44d3-94ba-c90a2d474984" /> Simple rotation components number in the 8-9k range per round, and each contains a needless callback datum as well. These do not need to hold any state and can be bespoke elements, and the proc to do things post_rotation can just be a normal atom proc. <details><summary>Still works as you'd expect, including items that have flag requirements like the wrench</summary>   </details> ## Why It's Good For The Game Makes a heavily used element much more lightweight, saves a few mb of memory. ## Changelog 🆑 refactor: simple rotation component has been refactored into an element Please report any bugs to github. /🆑
