Create a vertical 2:3 stylized 3D illustration of a cute chibi girl enthusiastically eating ramen, centered on a pure black background with no environment. The character is a glossy soft-vinyl toy-like figure with oversized rounded head, tiny sleepy half-closed eyes, small pursed lips, rounded cheeks, and pastel iridescent neon lighting in cyan, blue, purple, magenta, and pink gradients. She has {argument name="hair style" default="large rounded side-swept bangs with a high bun made of three soft bubble-like lobes"} and a simple short-sleeve shirt, all rendered as smooth matte clay/plastic surfaces with subtle subsurface softness. Pose her holding a large ramen bowl close to her chest with her right hand while her left hand lifts exactly 2 chopsticks, pulling a bundle of long wavy noodles upward into her mouth. The bowl contains exactly 6 visible food elements: 1 mound of wavy noodles, 1 pink-purple broth surface, 1 curved soup spoon on the left, 1 large oval egg half in the front-left, 1 smaller egg half on the right, and 1 upright rectangular nori sheet at the back-right. Use dramatic rim lighting and luminous color transitions across every form, high contrast against black, smooth rounded modeling, adorable surreal toy aesthetic, shallow shadows, crisp focus, no extra objects, no visible texture noise. Add a small handwritten signature and date in the bottom-right reading {argument name="signature text" default="July 27, 2026 Oyagi"}.
