Lena was working on a helper for the dashboard that combines two different sequences of light signals into a single output. Mark mentioned that whenever two active signals land in the same spot, they should move forward to create a new position, much like counting with simple on-off switches. For instance, if she merges a sequence of '11' with a single '1', the dashboard should display '100' as the final result. Eva checked the logic to ensure it would be a useful addition to their team's shared utility folder.
