An isometric 3D cube-shaped miniature room (perfect shallow cutaway cube, everything 100% strictly contained inside the cube boundary, no protrusion). Room description: Tony Stark's underground workshop during the Iron Man Mark 42 suit autonomous assembly process. Dimly lit high-tech garage lab: brushed steel and matte black walls covered with holographic blueprints, arc reactor glow, scattered tools (DUM-E robotic arm holding a coffee mug, U robotic arm spraying fire extinguisher), multiple half-assembled red-gold Iron Man suits hanging on robotic arms, a central rotating platform where the Mark 42 suit pieces are flying and auto-assembling onto a dummy Tony, sparks flying, welding arms active, floor littered with micro thrusters, faceplates, repulsor parts, empty whiskey glasses, and a glowing circular arc reactor prototype on the workbench. Wall has a large "Stark Industries" logo and Jarvis interface screens showing suit diagnostics. Character: chibi/figurine-style Tony Stark in black tank top, perfectly groomed goatee, matte PVC material, big head small body proportion, standing on the workbench with arms outstretched, confidently directing the autonomous suit pieces to assemble around the dummy, cocky satisfied smirk, one eyebrow raised, wearing welding goggles pushed up on forehead. Lighting: dramatic cinematic workshop atmosphere (cold blue holographic glow from screens + intense white welding sparks + signature arc reactor ice-blue light + warm orange workshop lamps), realistic metallic reflections, colored caustics and god rays cutting through light smoke. Camera: slightly elevated isometric three-quarter view, front edge of the cube perfectly centered and framed, shallow depth of field, foreground sharp, background softly blurred, photorealistic materials, ultra-high detail on every screw and reflection, clean museum-like composition, neutral dark backdrop, no text, no watermark, no elements outside the cube. 8K, masterpiece, best quality, Gemini 3 Pro Nano Banana Pro style
