Cinematic 4-panel storyboard for a business documentary scene set inside [an old metalworking factory filled with lathes and industrial machines], arranged in an exact 2x2 grid separated by clean thick white borders. No captions, speech bubbles, or text overlays. Panels: 1. Top-left: Extreme close-up of a metal lathe in operation, cutting a spinning cylindrical metal workpiece with glowing curled metal shavings flying outward; a gloved worker's hand and forearm appear in frame for scale against a softly blurred factory interior. 2. Top-right: Wide shot down the central aisle of the workshop; [a young Japanese businesswoman] in [a navy suit and white blouse] walks forward with purpose, while [an elderly Japanese craftsman in a gray work jacket and dark cap] works at a lathe in the midground surrounded by industrial equipment and piles of metal shavings. 3. Bottom-left: Tight portrait close-up of [a young Japanese businesswoman] looking directly into the camera with a calm, determined, serious expression, hair neatly tied back, framed against the dark, softly blurred industrial background. 4. Bottom-right: Medium two-shot showing [a young Japanese businesswoman] smiling and shaking hands with [an elderly Japanese craftsman in a gray work jacket and dark cap] in the workshop, illuminated by warm daylight from large factory windows, conveying trust and mutual respect. Style & Lighting: Photorealistic 35mm film stills, muted industrial color grading, high dynamic range, natural window daylight mixed with dim fluorescent tubes, gritty tactile metal textures, shallow depth of field. Mood is [serious, respectful, cinematic, documentary-like]. Consistent character appearances across all panels.
