科幻电影预告片提示：星云清算

Create a cohesive sci-fi movie trailer for "Nebula Reckoning" with an unified aesthetic. Write the prompts with Grok Imagine updated capabilities in mind, with consistent elements: a color palette of deep blues, purples, and neon accents, a futuristic and clean tone, cinematic widescreen composition (16:9), and recurring motifs like glowing tech, cosmic voids, and dynamic motion. These will flow together as a single narrative arc.
