Create ONE standalone premium website background, portrait 3:4, highest available native detail. Collection: Bluewater freight. Intended use: Mobile hero or tall editorial image. Scene and composition: PORTRAIT image. A distant cargo vessel near the bottom below a huge vertical expanse of silver-blue marine haze and midnight ocean, calm clean upper half for mobile headline. Style: Photorealistic high-end maritime editorial photography. Ink-navy ocean, cold silver mist, restrained steel blue and ivory. Realistic vessel engineering, natural sea physics, fine film grain. Atmospheric, expansive, quietly confident. Keep generous intentional negative space suited to this composition. Exquisite art direction, natural optics, very fine film grain, believable proportions and surfaces. This is an IMAGE ASSET, not a website screenshot.
