Use case: stylized-concept. Asset type: one premium RAITEC desktop wallpaper, full-bleed 16:9 landscape; request 3840x2160 pixels if available. Supplied image 1 is the official RAITEC logo for a flat crisp branding insert only. Retain exact wordmark RAITEC, crossed symbol, IT Services subline, original triangular facets, colors and proportions. Insert logo once at lower right, approximately 17% canvas width, 6% right margin and 12% bottom margin, in a quiet contrasting area. No other text, lettering, slogans, watermark, people, UI, monitor mockup or outer border. Palette navy #05345d, blue #334f76, slate #516f82 and #91a1af, amber orange #f7a824 and #faba57, porcelain/ivory white. Reserve left 38% as a calm icon-friendly field and keep bottom 8% low contrast for taskbar. High craft, a considered coherent artwork, not a collage of multiple wallpaper options. Style: breathtaking cinematic underwater fine-art photography with restrained fantasy lighting. One elegant translucent jellyfish floats in deep midnight-navy water on the upper-right; its broad slate-blue bell has delicate pale-blue radial veins and a subtle warm-amber bioluminescent rim. Several long thin graceful tentacles drift diagonally downward inside the right two thirds. Exquisite organic material, subtle suspended particles near the subject only, quiet mysterious depth, no seabed or surface horizon. Left 40% almost empty deep blue. A single organism, no schools of fish, no coral, no dense bubbles, no cartoon eyes, no rainbow neon. Original WHITE logo on undisturbed dark lower-right water, separated from tentacles.
