Minh họa avatar một nét tối giản

Transform the subject from the reference photo ([a person, cat, dog, or botanical plant]) into a minimalist continuous single-line art illustration tailored for a profile avatar. Reconstruct the most iconic outer contours and signature features using smooth, confident, flowing single-stroke lines with soft curves and relaxed vitality, avoiding stiff mechanical outlines. Render the line work in thin crisp white or light contrasting tone against a rich, solid [dark-toned matte] background. Accentuate with a few sparse, whimsical abstract geometric dots, miniature stars, or colorful specks around the subject to add charm and liveliness. Centered composition, balanced negative space, clean modern artistic aesthetic, 16:9 ratio. Avoid realistic rendering, heavy shading, complex textures, and cluttered backgrounds.
