Establishing reference photograph of a place: 2D hand-drawn illustration of a long, pristine white futuristic corridor at eye level, wide shot, symmetrical one-point perspective receding to a distant vanishing point. Smooth seamless white walls and glossy floor, recessed ceiling light panels casting soft volumetric white beams downward. Subtle deep navy accents in floor trim and wall seams, faint cool shadows along the edges. Empty, sterile, silent. Clinical white and deep navy palette, clean ink lines, flat cel shading, atmosphere of cold clinical tension. No people, no text.
No people, no visible text, no watermark.
