Use case: stylized-concept. Asset type: one RAITEC desktop wallpaper, full-bleed landscape 16:9; request 3840x2160 pixels if available. Input image 1 is the supplied original logo, used only as a crisp flat branding insert. Keep exact RAITEC wordmark, crossed symbol, IT Services subline, triangular facets, original proportions and colors. One logo at lower right, about 17% of canvas width, 6% right margin, 12% bottom margin, on a calm contrast-appropriate field. Only text is the supplied "RAITEC" and "IT Services"; no slogans or other writing. RAITEC palette navy #05345d, blue #334f76, slate #516f82 and #91a1af, orange #f7a824 and #faba57, warm white. Left 35-40% calm enough for desktop icons, bottom 8% clear enough for taskbar. Refined deliberate composition. No monitor mockup, UI, people, watermark, additional logos or poster border. Art direction: cinematic astronomical fine-art wallpaper, one grand sweeping nebula cloud made of deep slate-blue dust and delicate glowing warm amber-orange filaments concentrated on the right two thirds. A graceful diagonal tide of translucent gas shows rich organic turbulence, soft luminous depth and deep inky navy voids; plausible long-exposure space photography feeling with restrained contrast and just a few tiny scattered stars. No planets, no sun discs, no horizon, no spaceship, no astronauts, no rainbow colors, no neon purple, no lens flare. Left 40% calm almost-empty midnight navy. Lower-right quiet dark field for the supplied WHITE flat logo, undistorted and legible, not made from stars.
