<think>Target shape: cyan rectangle at (2, 0)
Distance from target shape to brown trapezoid at (1, 3): 4
Distance from target shape to red square at (3, 2): 3
Distance from target shape to pink square at (1, 1): 2
Distance from target shape to blue right_triangle at (1, 2): 3
Closest shape is the pink square at (1, 1) with distance 2</think>
