Prompt for this run
Show 20 numbered balls (1 to 20) dropping from the center of a heptagon that spins 360 degrees every 5 seconds. The balls are affected by gravity and friction, collide with each other, and bounce realistically off the rotating walls; show each ball's spin via the rotation of its number. Implement all collision detection yourself.

thinking
**Evaluating layout issues** I’m thinking about how the layout height might be causing overflow because of the minimum height of 600, which could be stretching the grid taller than it should be. The screenshot shows the footer off the bottom, which isn't ideal. I could improve it by adjusting the aside to a more compact height, maybe around 545, to accommodate smaller margins. It seems like a little tweak might help fix the issue, so I'll test it with some clicks.
