Edit image 1, the square aircraft UV texture atlas. Image 2 is the real Gripen photo reference for paint appearance only. Deliver ONLY the revised square atlas, at highest available resolution (2048 or higher). Preserve EXACT image 1 UV island silhouettes, positions, scale and every marking's position. Do NOT output a plane photograph or change layout. Match reference neutral gray matte paint, eliminate blue cyan tint. Pale light gray radome/nose, medium neutral gray fuselage/tail, subtle warmer gray upper surfaces. This is maintained aircraft with realistic restrained weathering: remove heavy speckled distressed paint everywhere, use smooth fine paint with delicate varied panel tones, fine narrow panel seams and tiny fasteners, mild downward rain streaks on fuselage sides, faint soot aft near exhaust and grime localized to hinges/access panels. No baked lighting/shadows, no raised bevels. Preserve crisp dark-gray 179 numbers, low visibility dark-gray circular Swedish three-crown insignia, FARA intake warning and small pale yellow rectangular rescue/service labels. Make all six three-crown roundels accurate and clean: thin gray circular outline and three small crown silhouettes arranged two above one below. Avoid thick black comic outlines. Keep both side profiles, four main wing UV pieces and four canard UV pieces registered exactly as image 1. Highly realistic PBR basecolor/albedo texture for flight simulator asset. No additional text, border, legend, camera, watermark.
