📋 Gallery Station Readiness Check

Teams assemble a polished station-ready version of the puzzle with final directions, solution guide, and a short creator card explaining what makes it satisfying to solve. A new tester or representative user completes the puzzle while the team observes silently, then teams give a brief walkthrough of their design journey from user evidence to revisions and remaining questions. The teacher uses a readiness rubric as a milestone gate for moving into the final gallery phase.
