Ran my full Meridian-9 launch → stage separation → booster return benchmark on Opus 5.5. The result is honestly insane. Multiple cinematic camera angles, launch physics, separation, onboard shots, RTLS + landing sequence — all from one massive @threejs prompt. Opus 5.5 is absolutely cooking on complex visual coding.
