Mechanical Bloom

Theme: "Mechanical Flower Bloom". Highlight the video-generation model's strengths in lighting, art detail, realism, camera movement, and cinematic character. The overall style is a high-end technology brand advertisement with strong visual impact. Use a one-shot macro push-in: begin with a metal flower bud in darkness, gradually enter the precision mechanical structure inside the petals, and end with the mechanical flower fully blooming as light spreads outward in a climactic frame. Require realistic physical lighting, refined metal and glass materials, delicate mechanical motion, stable composition, cinematic color grading, and no text.
