A single cohesive isometric floor platform: Top-down strategy game island inspired by classic mobile base-building games, enormous perfectly flat bright-green grass center with almost no elevation changes, rocks, obstacles, hills, rivers, or terrain clutter, designed as a clean open buildable field. Large square-like central plateau occupying 85–90% of the island, surrounded by a thin tropical island border with crystal-clear blue water, sandy beaches, and lush vegetation. The outermost edges gradually transition into a dark apocalyptic robotic biome featuring black obsidian cliffs, glowing purple energy fissures, ancient AI ruins, rusted mech skeletons, broken cybernetic towers, and twisted metallic jungle. Strong contrast between the peaceful vibrant green build area and the corrupted black-and-purple perimeter. Highly polished mobile game environment, colorful and readable, premium game art, AAA strategy game quality, cinematic lighting, no buildings, no troops, no UI, maximum empty buildable terrain, clean symmetrical layout, paradise island surrounded by an encroaching robotic apocalypse., viewed top-down in true 2:1 isometric (dimetric) projection. One compact diamond-shaped island/platform of terrain seen from above, with a little thickness/depth at the edges, clean stylized low-poly, vibrant art style, soft light from the upper-left. The whole platform is centered with an even margin around it and fully inside the frame. solid flat pure magenta background, RGB 255 0 255 (#ff00ff), fill the ENTIRE background with this one magenta colour — NOT transparent, NO checkerboard pattern, no gradient. No sky, no horizon line, no characters, no buildings unless implied by the theme, no text.
