Image: A wide horizontal 2D side-scroller game TRANSITION

Generated from: A wide horizontal 2D side-scroller game TRANSITION STRIP showing a school building doorway seen from the side, ONE SINGLE CONTINUOUS drawing. From LEFT to RIGHT: (1) the left half is INTERIOR: a warm wooden hallway floor whose walkable surface band is at the top, then immediately below it a DARK WOODEN BASEBOARD strip, then below that a wooden panel skirting wall going down; (2) in the middle, a slim vertical door jamb marking the threshold; (3) the right half is EXTERIOR: a light gray CONCRETE pavement whose walkable surface band is at EXACTLY THE SAME HEIGHT as the wooden one, then immediately below it a CONCRETE BASEBOARD strip of EXACTLY THE SAME THICKNESS as the wooden baseboard and perfectly aligned with it, then below that a concrete kerb wall going down. CRITICAL: the surface line, the baseboard top line and the baseboard bottom line must be perfectly continuous straight horizontal lines running across the whole image, matching on both sides of the threshold. Both materials richly textured — visible wood grain and planks on the left, visible concrete grain and subtle joints on the right. Painted in the polished style of top endless-runner mobile games: soft gradients, glossy highlights, gentle ambient occlusion. No sky, no wall above, no characters, no text — only the floor band, baseboard and skirting.
