Hey, thanks for the contribution! We just need two quick fixes before moving forward:

Scope: Could you revert the changes in toggle-group.tsx? We try to keep PRs focused on one task to make auditing easier.

The Registry Flow: Since we use a registry system, changes need to be made in the source files at apps/ui/registry/default/ui. Once you've made your edits, run this command string from apps/ui to update the generated components:

bun format:all && bun registry:build && bun ui:sync

You can find the full breakdown of the registry architecture in the CONTRIBUTING.md.
