这是一张游戏社群的 Discord 服务器横幅，采用霓虹夜景风格，没有文字。两台发光的街机立在湿漉漉的天台上，下面是紫光笼罩的城市，厚重的紫色云层让顶部保持安静。可以换成你服务器的主题，顶部写服务器名的地方保持简洁。

Create a finished 16:9 Discord server banner for a gaming community. No text, letters, numbers, logos, interface elements, or watermarks. Show a nighttime cyberpunk city rooftop: two glowing arcade cabinets grouped in the lower-middle foreground, their screens casting cyan and magenta light onto wet rooftop concrete; distant neon towers sit low on the horizon. Broad violet clouds fill the sky. Keep the top 20% especially calm and uncluttered, with only soft purple cloud forms and dark open sky; no signage, bright details, or small objects along the top edge. Place all high-contrast focal detail in the central and lower portions. Use a near-black navy base with electric cyan and hot magenta neon accents, violet cloud illumination, subtle atmospheric haze, restrained rain reflections, and clear foreground/background separation. Render crisp, readable arcade silhouettes and large simple light shapes that remain clear at phone-banner scale. Wide cinematic composition, polished game key art, controlled bloom, high contrast, no busy detail behind the main scene.
