"OVERCLOCKED" 是一张 72 小时射击游戏直播马拉松的活动横幅，采用赛博朋克霓虹风格。带粉色点缀的青色描边字母在雨夜小巷中发光，上方是活动名称，下方是日期和频道链接。可以换成你自己的活动名、日期和链接再做一张。

Create a 16:9 Twitch channel banner for a live competitive shooter marathon. Exact rendered text, preserve spelling and punctuation: Primary headline, enormous: "OVERCLOCKED" Secondary line: "SHOOTER MARATHON · 72 HOURS LIVE" Details line: "SEPT 18–20, 2026 · TWITCH.TV/OVERCLOCKED" Micro callout: "LIVE // NO RESPAWNS" Composition: near-black cyberpunk city alley at night, built for a wide Twitch header. Keep all copy inside a centered safe area spanning 12% to 88% width and 18% to 78% height. "OVERCLOCKED" dominates the middle, nearly full width, in a single line. Construct every letter as precision angular glass neon tubing with a medium-wide bold geometric skeleton: 45-degree slash-cut terminals, acute vertices, diagonal shear ends, and diamond-shaped negative-space cuts at intersections. Tubes are cold chrome-framed transparent glass, bright electric cyan core with selected slash segments switching to hot magenta; show tube wall thickness, internal electrode seams, uneven voltage pulses, fine cyan-white plasma crawling along letter perimeters, and tiny electrical sparks at cut corners. No rounded lettering. Set the secondary line tightly above the headline in compact angular chrome type; place the date and channel URL beneath in sharply spaced cyan-white technical lettering; put "LIVE // NO RESPAWNS" small at lower right in magenta. Background: rain-slicked black asphalt, faint circuit-grid pavement markings, distant holographic panels without readable words, low steam vents, mirrored cyan and magenta tube reflections beneath the headline. Cold blue-white overhead arc light; cyan neon fill from left, magenta neon fill from right. Add vivid RGB chromatic aberration on every hard edge: cyan offset 4px left, magenta offset 4px right. Fine horizontal scan lines every 15–20px at 25% opacity across the full image. Add three narrow horizontal CRT glitch slices shifting 6–8px right across portions of the headline and background. Palette restricted to #00E5FF electric cyan, #FF00FF hot magenta, #C0C0C0 cold chrome, near-black and deep blue shadow. High contrast, razor-sharp typography, cinematic rain haze, no warm colors, no people, no weapons, no logos, no extra readable text.
