A 15-second cinematic video. On an old wooden desk in a bright sunlit room filled with clear morning light, a magical mechanical bird is created through rapid self-assembly. The bird is visually striking: polished silver and brass body, luminous blue core, jewel-like eyes, and translucent stained-glass wings. Keep the story simple: fast assembly, vivid awakening, dramatic flight. Small metal parts, gears, and glowing fragments swirl through the air and snap together into the bird in a beautiful time-lapse-like sequence. Its core begins to pulse, its eyes light up, and its wings spread open with energy. Then it bursts upward, scattering dust and sparkling particles, and flies quickly toward a large bright window. Use energetic cinematic camera movement: overhead assembly shot, extreme macro details, sudden push-in, short orbit, low-angle rise, and a dramatic final pull-back to a wide shot filled with sunlight. Bright clear morning sunlight, airy atmosphere, clean highlights, crisp reflections, vivid light, elegant motion, strong visual impact, no text, no logo. The room should feel bright and fresh, not dark, not cloudy, not gray or muted. No background music. Sound effects only.
