📖 How to Use This Simulation
Step 1: Select a wall material (glass, plastic, brick, or open air).
Step 2: Select a floor color (black, gray, or white) to change how much light is absorbed.
Step 3: Click "Run 10-Minute Simulation" to see how hot your structure gets!
Key concept: Glass lets visible light in but traps infrared (heat) radiation — just like greenhouse gases in Earth's atmosphere!
