Ciclo dia e noite de Lantern Hour: Kimi vs Opus

Do post

I put Opus 5.5 and Kimi K3.1 Pro head-to-head with the exact same coding challenge. Build "Lantern Hour" in a single HTML file: 4 art styles, a full day/night cycle, dynamic lighting and shadows, and interactive controls. Canvas 2D only. No libraries or external assets. Which one did better?
