Overhead Leopard in Blue Marble Swirls

Create a vertical fine-art illustration of exactly 1 leopard viewed from directly overhead, walking steadily downward through a luminous abstract marbled surface. The leopard should be centered on the canvas, full body visible from tail to front paws, with its head near the lower middle and its long tail curling upward toward the top; realistic golden fur with dense black rosettes, muscular back, small rounded ears, focused downward gaze, and one front paw stepping forward. Surround the animal with a white marble-like background filled with fluid ink swirls and eddies in pale sky blue, vivid cobalt blue, and a few tiny warm gold speckles, as if the leopard is moving through swirling water, paint, or cloudlike currents. Use a clean high-key palette, delicate linework, elegant negative space, crisp detail on the leopard, soft painterly motion in the marbling, and a serene inspirational mood. Add small unobtrusive text in the bottom-right corner reading date_text with a tiny cursive signature beneath it reading signature. The subject is animal; the main accent color in the marbled currents is accent_color. No border, no frame, no extra animals, no large typography, no photorealistic environment.
