ゲーム配信用の背景で、レトロなゲームセンターのスタイルです。明るい画面が光るアーケード筐体の列が、あたたかいつりランプの下で右側に続き、その光がつやのある白黒の市松模様の床に映り、左の暗い無地の壁はカメラ用に空けてあります。

Create a polished 16:9 stream background for a retro arcade, designed to sit behind a webcam or VTuber model for long viewing sessions. Show a row of classic upright arcade cabinets with softly glowing screens and colored cabinet lights, mostly arranged across the center-right and far-right of the scene. Use a black-and-cream checkered floor receding in perspective toward the back wall. Keep the left 38% of the frame calm, dark, and low-detail for a camera overlay: a softly lit charcoal wall and mostly open floor, with no cabinets, bright hotspots, or high-contrast patterns behind the person. Apply gentle depth-of-field softness to the cabinets and distant room while keeping the floor pattern subdued; do not blur the camera zone into visual noise. Retro gaming register, near-black room, muted teal and amber cabinet glow, restrained magenta accents, soft atmospheric haze, controlled bloom, realistic materials, cinematic wide-angle interior composition, clean separation between foreground and background. No text, letters, logos, signage, UI, people, or characters anywhere. Keep all visual detail away from the left camera area; no flicker-like effects or excessively bright lights.
