Hi, Currently, we have some pending commits from the upstream `csstree` repository: <img width="934" height="74" alt="Image" src="https://github.com/user-attachments/assets/ddd871a7-6155-47ac-8584-d654fa629018" /> It looks like there are some changes from the original `csstree` repository. What is our policy regarding upstream commits for the forked `csstree` repository? Do we discard them, or merge them in when needed?
