金字塔机器人跨场景转场：首尾帧一致性控制

First-to-last frame demo with two contrasting scenes. Frame 1: a sleek humanoid robot with Egyptian pharaoh-style ornamentation stands at the base of a massive ancient pyramid under a dramatic sky, wide establishing shot, dust particles in shafts of golden light. Frame 2: the same robot stands in a pristine white futuristic corridor alongside a human figure, clean geometric architecture, cool clinical lighting. Seedance interpolates the 8s transition between these two worlds — ancient stone dissolves into polished surfaces, warm amber shifts to cool white, sand becomes reflective flooring. Keep the robot appearance consistent throughout, blending sci-fi precision with ancient-world atmosphere.
