Generate a clean, readable top-down concept art of a compact three-lane fantasy battlefield called Green Fork. Show a broad central safe route, two parallel side routes with slight height changes, a small wooden crossing at the center, a camp sign landmark, grass terrain and scattered trees and rocks. Keep the three routes visually separated and leave clear walkable corridors for characters. Friendly colorful hand-painted 3D game concept style, soft daylight, warm green and sand palette, orthographic top-down composition, no perspective distortion. This is a design reference board, not a screenshot: no UI, no labels, no letters, no numbers, no watermark, no people, no text, no logo."
