Create a vertical 3:4 low angle photorealistic CGI view of an impossibly tall modular postal processing tower against a clear saturated cobalt blue sky. Stack large crisp industrial cabinets tightly through the center: a white silver cabinet near the top, a vivid red block below it, yellow and green blocks down the left, a dominant royal blue cabinet projecting to the right at mid height, and silver cabinets descending into the cropped bottom. The blue cabinet carries a white geometric postal eagle emblem and two compact left aligned lines reading UNITED STATES, POSTAL DELIVERY. A second eagle emblem sits on an adjacent white panel with a thin red underline. Keep the lettering small as in an industrial brand mark. Metal stair flights and grated balconies zigzag down the left, bordered by thin silver safety railings. A steel roller conveyor projects from the upper right into the sky, with chrome circular rollers and a dark belt. Another large conveyor and deep blue enclosure enter from the cropped upper left. Add narrow vertical green and orange service pipes, cabinet hinges, vents, bolts, chrome fittings and tiny red status lights. A small white parcel rides on the upper right conveyor; its tiny shipping marks stay indistinct. Perspective lines converge upward, with the machine cropped at top left and bottom, and generous blue sky at upper right. Strong sunlight from the upper left creates glossy metal highlights, hard realistic shadows and vivid red, yellow, green and blue enamel surfaces. Fine photographic grain. No people, road scene or added caption.
