"Violet//Void" 是一张深夜游戏频道的 Twitch 个人资料横幅，采用紫色赛博朋克风格。泛紫光的铬金属字和一句短标语、一行「追随信号」放在左边，右边霓虹城市里坐着一个戴发光耳机的兜帽人影。可以换成你自己的频道名和标语。

Create a finished Twitch channel banner in a 21:9 wide composition. Purple leads the cyberpunk palette. Keep every text block within the central safe area with generous outer margins; reserve the right third for a distinct hero scene. Use a deep aubergine-to-near-black city backdrop with violet haze, rain-slick reflective surfaces, blurred neon signage and fine circuit-grid details. Violet is the dominant light and reflection color, with electric cyan and hot magenta as sharp secondary accents and cold chrome highlights. Render these exact strings, spelled precisely, with no additional text: headline “VIOLET//VOID”; supporting line “GAMES AFTER DARK”; small channel label “TWITCH • LIVE CHANNEL”; call to action “FOLLOW THE SIGNAL”. Set “VIOLET//VOID” largest on the left, on one line, in custom bold medium-wide angular display lettering. Construct the letters like laser-cut aerospace-grade metal plate, with deliberate 45-degree slash cuts, sharp shear-face stroke endings, acute vertices and diamond-shaped counters. Give the cold chrome faces strong violet reflections; show fine machined striations and crisp bevels. Let light refract and reflect within the beveled edges. Add RGB chromatic aberration to hard edges, cyan offset 4px left and magenta 4px right. Run fine horizontal scan-line cuts across all surfaces, with 2–3 narrow glitch slices shifted right 6–8px. Trace select letter edges with electric cyan-white plasma threads. Keep the supporting line and details smaller, sharply legible, in clean geometric sans lettering. On the right, show a three-quarter-view anonymous streamer silhouette wearing a hard-surface headset, framed by a rain-soaked neon alley and stacked holographic panels; purple rim light defines the figure, with restrained cyan and magenta edge lights. Add wet-ground reflections that echo the title’s purple and chrome. High-contrast cinematic lighting, precise metallic surfaces, controlled neon bloom, subtle atmospheric fog, ray-traced reflections, detailed 3D render. Strong text readability at banner size; no extra logos, text, borders or watermarks.
