🏗️ Version 3 Ecosystem & Iteration Log

Teams build a higher-fidelity Version 3 of their ecosystem using sturdier materials, clearer printed labels, and finalized interactive elements. They complete their iteration log documenting Version 1, Version 2, and Version 3 with photos, feedback summaries, and explanations of what changed and why. Teams conduct a brief peer check with one other group to confirm clarity before moving to the presentation phase.
