Ultra-Cinematic Continuous One-Shot: Impossible Staircase

Create a 30-second ultra-cinematic continuous one-shot of a man endlessly climbing one impossible staircase that physically transforms beneath his feet. Start in a crowded subway station as he sprints upward. Without cuts, portals, fades, or teleportation, the same stairs organically evolve: subway concrete stairs → luxury skyscraper staircase → stadium seating → medieval castle spiral stairs → giant pyramid steps → snowy mountain trail → massive tree branches → spacecraft ladder above Earth → impossible staircase returning to the original subway. Every transformation happens while he is still climbing: concrete cracks into stone, railings reshape while he holds them, steps widen, narrow, break, become rocks, roots, branches, then metal rungs. Keep his movement dynamic: sprinting two steps at a time, swinging around railings, jumping gaps, scrambling on rock, climbing branches, pulling himself upward, and using magnetic spacecraft rungs. Dynamic continuous camera: front tracking, low behind feet, overhead, orbiting spiral stairs and tree trunk, cliff top-down shot, then floating around him in space. At the end he reaches a platform above Earth, exhausted. A staircase suddenly unfolds downward from empty space, leading back to the same subway station. Commuters calmly descend. One gestures for him to move. He sighs, grabs the railing, and starts climbing again. Most important: one staircase, one uninterrupted upward journey, seamless physical transformations, no disconnected environments.
