Image: Wide 2D side-scroller game BACKGROUND of a school

Generated from: Wide 2D side-scroller game BACKGROUND of a school CLASSROOM interior, ONE SINGLE CONTINUOUS room in one horizontal scene — do NOT split the image into panels or rows. Flat straight-on elevation view, no perspective. COMPOSITION RULES: (1) the LEFTMOST 120 pixels and RIGHTMOST 120 pixels contain ONLY plain empty wall with the same horizontal trim lines that cross the whole image — no furniture, windows or boards in these edge zones; (2) the FLOOR LINE sits at exactly 65 percent from the top; below it warm glossy wooden floorboards; (3) middle zone only: one large green chalkboard, two tall windows with sunlight and trees, a colorful alphabet border along the top, pinned children's drawings. Painted in the polished style of top endless-runner mobile games: rich saturated colors, soft gradients, glossy highlights, subtle ambient occlusion, appealing rounded shapes, cohesive warm lighting, high production value. No frame lines, no characters, no text.
