Tile Contínuo de Mapa em Pixel Art Retrô

Using the reference image containing [five vertical strips of a retro pixel-art game map separated by white gaps], reconstruct and merge it into a single seamless square tile. Remove all white separator lines completely. Extend the terrain features—including [green forests, blue water bodies, orange roads, and grey castle structures]—horizontally to bridge the empty spaces, blending the edges naturally into adjacent sections. Produce a continuous, unified retro pixel-art overworld map texture with crisp pixels and no visible seams or artifacts.
