Image: Production-quality 2D illustrated background plate

Generated from: Production-quality 2D illustrated background plate for a fixed-landscape mobile game, exact wide 1560x720 composition, no UI, no text, no readable signs, no characters. Setting: a steampunk Joseon fantasy frontier settlement at Busanpo formed around the mysterious Lab021 Gate. This is a town hub backdrop stage, intentionally leaving clear empty spaces for four clickable building PNG overlays. Use a cinematic ink-wash and painterly style: misty harbor air, distant Joseon roofs and scaffolds, brass pipes, jade-blue gate glow haze in the distance, wet stone ground, lantern pools, hanji cloth awnings, subtle mountain/sea silhouettes. Do not place a huge central gate or main buildings; keep it as an atmospheric base layer with readable ground plane and depth. Premium hand-painted game art, thin ink linework, warm lanterns, cold cyan mystery light, mobile readable, no pixel art, no SVG look.
