Create a graphic dimensional ribbon coil on a flat near black charcoal background, canvas 4096 by 3648, landscape ratio 64:57. A huge lavender coil of wide flat ribbon occupies roughly the left four fifths; retain a tall uninterrupted dark negative space strip at the right. Its axis is nearly vertical and slightly leaning. Show two major dark elliptical hollow openings with partial neighboring turns clipped by the upper and lower frame edges. The broad coil sweeps outside the left edge. It is a continuous broad band wound into stacked hollow rings, not a round wire spring, torus pile or thin line spiral.
Each turn has a thin pale lilac flat upper rim with clean vector edges, a thicker lavender outer vertical wall, and a curved inner wall visible inside its elliptical opening. Use tightly organized rows of black circular halftone dots on the inner curved surfaces, their size and spacing creating stepped curvature and shade. On the outer walls scatter broken black grit and small triangular flecks, especially toward the right facing shaded edges. Keep these irregular surface marks distinct from the regular dot screen inside. The hollow cores are nearly black with sharp silhouettes; the lightest rims are narrow and never white glowing tubes. Pale violet front surfaces and deeper violet sides supply depth without photographic gradients. Static oblique elevated view, clean flat color shapes with print texture and bold dimensional geometry.
Negative constraints: round tubular spring, rainbow colors, metallic reflections, glass, glossy CGI, soft blurred shading, centered small object, complete uncropped coil, text, logo, ground shadow, border.
