PowerJob concept cover prompt

Create a restrained 16:9 editorial cover for a Chinese technical guide about PowerJob. Show one central scheduling console coordinating several distinct Java business services, with a few tasks splitting into parallel worker jobs and a small DAG workflow visible as precise connection lines. Use a light neutral background, charcoal structure, restrained green and amber status accents, crisp high-contrast labels, and no gradients or decorative blobs. Do not copy third-party logos, do not invent a product screenshot, and do not include credentials, code, or performance claims. The image should communicate centralized scheduling with distributed execution while leaving clear space for a title. This remains prompt-only until image generation is explicitly requested.
