Create ONE standalone premium website background, portrait 3:4, highest available native detail. Collection: Port geometry. Intended use: Mobile hero or tall editorial image. Scene and composition: PORTRAIT image. Looking upward between tall orderly container stacks, warm red left and muted blue right, a generous pale sky opening across top half, no lettering. Style: Premium industrial editorial photography with impeccable architectural geometry. Warm vermilion shipping containers, faded cobalt, off-white cranes, pale concrete and clear cool sky. Tactile painted steel, restrained graphic color blocking, believable engineering. No fantastical equipment. 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. No words, numbers, lettering, logos, watermarks, UI, borders, collages or inset pictures. Do not add a title or any typography.
