Gave Gemini a raw AI Studio export and one sentence: "Get this off the ground and push it to GitHub like we've done on the other projects." No architecture spec, no feature list, no design brief. The model read the export, identified 5 dead dependencies (@google/genai, express, dotenv, cors, scaffold CSS), stripped them all, restructured a 293-line single-component React app around a periodic table grid, and fixed the particle animation that was broken because the original export used Date.now() instead of proper Framer Motion keyframe arrays. 75 elements across 8 categories, each with its own CSS custom property color. The whole thing — audit, fix, document, screenshot, push — happened in one 16-minute conversation with 3 user turns. Two of those turns were "approved" and "clean up." I mostly watched.
