Hey @Swetanegi05! This PR modifies package-lock.json — this project uses bun.lock exclusively and package-lock.json should not be present or modified.

Please remove it entirely:

rm package-lock.json
git add package-lock.json
git commit -m "chore: remove package-lock.json"
git push

Once that is resolved and CI passes, the flip controls implementation will be reviewed!

Hey @Swetanegi05! This PR had merge conflicts with main — I've resolved them automatically and pushed. Conflicts were resolved by keeping main's versions of core files while preserving your feature changes. CI has been re-triggered. Once it passes, we'll review for merge!
