(This one isn't that important, it's just easier for bookkeeping.) <img width="673" height="867" alt="Image" src="https://github.com/user-attachments/assets/bcf90751-a2be-451d-8351-ef69bc00499d" /> <img width="1083" height="658" alt="Image" src="https://github.com/user-attachments/assets/0ba083e6-1674-4aef-8d2a-28311bfc26a2" />
