🧱 Cardboard Market Prototype Build

In teams, students create a low-fidelity 3D prototype of their Healthy Food Access Design (mini store, mobile market cart, or garden plan) using cardboard, paper, play food, and price tags. They must include labeled roles (farmer, store, customer), a visible farm → store → table path, and sample prices sorted into low/medium/high. Teams attach a simple iteration log page with drawings showing what their idea is supposed to help users do.
