Cat illustration minimalist neon elegant.

Please convert the input image into a minimalist single-line illustration suitable for a social media avatar, with a default aspect ratio of 1:1. The subject can be a person, cat, dog, other animal, or plant. Based on the type of input subject, automatically extract the most recognizable outer contour and key features, and summarize them into an artistic minimalist single-line avatar/illustration. The overall goal is not mechanical outlining, but to preserve the subject's spirit and recognizability, reconstructing it through a single line in a more elegant and spirited way. [Subject Processing Logic] If the subject is a person: retain key contours such as face shape, forehead, nose bridge transition, mouth transition, chin, ears, hairstyle, etc., only keep necessary facial features, avoiding cluttered details. If the subject is an animal: retain head shape, ears, mouth and nose contour, gaze, and main direction of fur, avoiding complex details. If the subject is a plant: retain the most recognizable morphological features of flowers, leaves, branches, or fruits, using concise lines to summarize their posture and rhythm. [Line Style Requirements] Lines must be rounded, smooth, bold, and natural, as continuous as possible, with a sense of breathing and improvisation. Mainly use soft curves, avoid sharp, stiff, or rigid lines. Do not draw a rigid logo-style outline. Lines should be concise and full of vitality, with a touch of casual artistic flair, looking relaxed and collectible. [Composition and Avatar Adaptation] 1:1 square design. The subject should be clear, concentrated, and prominent. Use a centered or slightly offset composition, with a clear visual focus and ample negative space. [Background Logic] Do not fix the color to a certain one (not necessarily always blue). Choose a dark tone background logic based on the image's temperament. Avoid neon colors or cheap bright colors. [Line Color Logic] Use thin white lines or light-colored lines that contrast with the background. [Embellishment Logic] Add a small number of random colored dots, arcs, stars, or geometric symbols to enhance spirit and fun. Keep it sparse and natural. [Overall Goal] Minimalist, light, modern, and artistic. Suitable for social media: eye-catching, easy to recognize, and interesting. [Avoid] Realism, shadows, textures, complex scenes, mechanical outlining. Aspect ratio 16:9.
