A clean front-facing ID-style portrait of one cheerful adult Shiba Inu sitting upright against a seamless soft sky-blue studio background. Center the head and upper chest in a square symmetrical frame, keep both ears fully visible with even margin, align the eyes precisely and use a relaxed closed-mouth expression. Large softbox lighting creates friendly even illumination and tiny natural catchlights. Render true sesame fur layers, realistic whiskers, nose and canine anatomy with clean edges. No collar tag, no props, no text, no logo, no watermark.
