A pristine, rectangular white cardboard box centered on a gradient gray background that transitions from light gray at the top to dark gray at the bottom. The box is sealed, unbranded, with clean edges, matte finish, and no logos or markings. Soft, diffused lighting from above and to the left casts subtle shadows, creating gentle falloff on the right side. Even, neutral lighting emphasizes the box’s geometric shape and slight texture. Background is softly blurred for shallow depth of field, isolating the box. Full-color, neutral color grading with realistic, clinical aesthetic. Sterile, minimalist atmosphere typical of product presentation. Thick, high-quality cardboard material with visible surface texture. Eye-level perspective, crisp high-resolution photorealism, square aspect ratio, no props or distortions.
