Prompt
A Memphis cosmos of geometric motifs scattered across a dark cool-gray background that reads like a night sky, with the background occupying roughly the upper two-thirds of the 3:2 frame and providing deep negative space in the right third. Multiple Memphis elements are distributed across the canvas: one large angular zigzag in the left third, two medium rounded blobs in the lower-center and lower-right thirds, and a field of small circular and pinstripe motifs scattered through the upper-left and upper-right quadrants, while the exact center remains visually open with a small floating accent. Render each element as crisp vector shapes with flat fills and sharp edges, mixing hard-edged triangles, rounded rectangles, and thin linear strokes to preserve Memphis geometry. Apply metallic-texture effects to select shapes so silver, warm gold, and burnished copper surfaces show subtle brushed grain and thin specular highlights that read like foil under cool ambient light. Keep light neutral-cool so metallic highlights sparkle without warm bloom and soft, narrow glints define edges and cast minimal vector shadows. Compose for a horizontal 3:2 aspect ratio with tight safe margins, framing the largest shape to fill about one-quarter of the width so the overall layout reads well at poster scale.
