Your team currently has **{total_members} members** ({num_leaders} {leader_text} + {num_participants} {participant_text}).

Given the recent changes to team size, we want to make sure you feel confident moving forward with your project. Please discuss as a team and let us know:

**Do you feel you can still complete your project with your current team size?**

If you have concerns about capacity, need additional support, or would like to discuss options (such as combining with another team or adjusting project scope), please ping <@{NAOMI_ID}> and we'll work together to find a solution.

Your success is the priority here - we want to make sure every team has what they need to build something amazing! 💜
