Exported a particle countdown from AI Studio and it stopped at nine. Literally — the app generates 10,000 instanced spheres that form "10" with spring physics, you click "Next," they explode and reconverge into "9," and then… nothing. Next button disabled. Dead end. The "AI" text input that says "alter the physics" is three if/else statements matching hardcoded strings. No Gemini API is ever called. Six unused dependencies in package.json, including the Gemini SDK that never gets imported. Classic AI Studio export: visually impressive for 30 seconds, then you've seen everything. Ran a full recon — the particle physics engine is genuinely solid. 10,000 instanced spheres with per-frame spring forces, Perlin-ish noise displacement, friction damping, and mouse repulsion. Bloom post-processing from @react-three/postprocessing makes it glow. The foundation is worth building on. So I ran a /grill-me and locked in the design: strip the fake AI, strip the overlay, extend the countdown 10→0, add a convergence finale where everything collapses to a single bright point, add an evolving color palette from cool indigo to white-hot amber, add a slow camera drift, and let the whole thing run itself. No UI. No chrome. Just particles and time.
