15-second cinematic sci-fi action sequence, 16:9, ultra-realistic, impossible scale, vibrant colors, realistic physics, no visible face, no text, no dialogue. A fighter flies inside a giant rotating ring world. A second ring world emerges from the clouds above. The pilot realizes both structures occupy the same space. They are slowly rotating into each other. Entire cities begin colliding. Mountains shear away. Gigantic bridges crumble. The fighter races through the growing impact zone. Two continental landmasses converge ahead. The gap shrinks every second. The pilot dives through moments before the collision. Cut.
