Generated from: A seamless deep-ocean background for a strategic world map, equirectangular (Plate Carrée) projection, 16:9. Pure ocean only — NO landmasses, NO continents, NO islands, NO coastlines, NO text, NO labels, NO compass, NO grid numbers. Deep desaturated navy blue (#0B1421) darkest at the equator, gradually lightening toward the top and bottom edges into pale steel blue and finally near-white pack ice and frozen drift at the extreme north and south. Faint horizontal latitude bands every 20 degrees rendered as very subtle lighter lines, plus faint vertical longitude lines, both at low opacity like an old nautical chart. Soft mottled water depth variation, a few thin pale ice floes drifting in the far northern and southern waters. Flat vector-ish cartography style, matte, no lighting direction, no vignette, no noise grain, no watermark. Muted cold palette only. The image must be a uniform rectangular field that tiles horizontally without a visible seam.
