"SubSecond" は、RTAチャンネル向けの、スピード感のあるTwitchプロフィールバナーです。斜体の黄色い立体文字と「毎日世界記録に挑戦」の一行がストップウォッチのような輪の中で左にあり、右へ向かって黄色と青のスピード線が濃い青の背景を走ります。自分の名前と目標で作り直せます。

Create a finished Twitch profile banner, 2384 × 1024 px, 21:9. Use only these exact rendered words, with identical spelling and capitalization: headline “SubSecond”; supporting line “World record attempts daily”. No other text, numbers, logos, interface elements, handles, or URLs. Place all text and key graphics in the left half, vertically centered and within a generous safe margin. Make “SubSecond” the unmistakable hero, large and highly legible at phone-thumbnail size; set the supporting line beneath it, smaller but still clear. Use custom italic speed-display lettering: extra-bold, forward-slanted geometric sans forms, broad strokes, tight tracking, clean open counters, and sharp forward-cut terminals. Fill the letter faces with saturated electric yellow, add a restrained pale-yellow edge highlight and compact deep-blue extrusion; keep contours crisp and avoid glow that softens readability. Build a dark navy-blue scene with layered, sharply defined electric-yellow motion streaks sweeping horizontally from left to right. Add a large, partial abstract timing-ring / speedometer arc behind and beside the headline, without numerals, ticks, or text. Keep the area behind the words quiet and high-contrast. Let the motion streaks and subtle blue gradients continue across the right half as flexible background atmosphere; no essential information there. Controlled directional rim light, fine low-contrast surface grain, crisp digital rendering, high contrast, clean edges. Do not add any words beyond the two exact strings specified.
