  "prompt": "Create a single game texture atlas, EXACT 2 by 2 equal square tiles filling the entire square image edge to edge, no gutters, no labels, no text. Four distinct overhead spaceship ROOM INTERIOR floor textures to overlay within existing rooms. Strict orthographic vertical TOP DOWN, no isometric, no visible outer walls, no exterior, each tile fills entire quadrant with continuous grey worn metal floor and furniture. Same high fidelity gritty realistic sci-fi painted 3D game art as reference image, charcoal metal, muted red, warm amber lamps, cyan monitors, subtle shadows. TOP LEFT: scientific laboratory with white metal experiment benches around edges, microscopes, specimen vials, central clean examination table, blue screens. TOP RIGHT: alien research department, central green glowing cylindrical containment tank with strange small alien organism seen from directly above, sealed sample cases, scanners and biohazard equipment along edges, subtle green lighting. BOTTOM LEFT: module storage room with orderly racks and crates of spaceship components along sides, three distinct modules on work pallets, overhead view mechanical hardware, amber lights and central walking space. BOTTOM RIGHT: cozy small crew cabin, bed along left wall with dark teal blanket and pillow, desk with screen top right, locker bottom right, chair and personal items, warm bedside lamp, grey floor. Each quadrant is a fully equipped separate floor tile, no borders crossing into adjacent tiles. Furniture clearly readable at small game scale. Match provided frigate interior style. Reference image is STYLE ONLY; create new atlas, do not reproduce ship."
