Holiday hall artwork generated with the built-in OpenAI image-generation tool.
Prompt: Use case: stylized-concept. Asset type: wide holiday chess game background. Create an atmospheric, beautifully detailed winter holiday great hall in a gothic robot castle: snowy arched windows, evergreen garlands with warm tiny lights, crimson ribbons, brass candlelight, frosted pine branches framing the sides, polished dark wooden tabletop across lower half. Cinematic painted game art, rich evergreen, burgundy and antique gold, cool moonlight outside. Keep central area calm and dark so a functional chessboard UI can overlay it. No chessboard or chess pieces, no people, no text, no logos. Landscape 1536x1024.
