Dark cavern backdrop

Generated from: Video game backdrop for an Undertale homage fan game boss battle (original drawing, not a copy). Dark cavern / judgement-hall atmosphere: pitch-dark very deep blue-purple vertical gradient, subtle coarse pixel dithering texture so it is not flat, faint dim cold torchlight glow near the top, corners darker to form a subtle vignette. No characters, no text, no watermark. Flat pixel-art style full-scene background, horizontal 4:3 framing, dark and moody so bright UI elements pop.
