シャープな水平分割のミニマル・スプリットスクリーンレイアウト

COMPOSITION FINAL: strict 50/50 diptych, top 50% and bottom 50%, two separate scenes meeting exactly along a clean invisible horizontal line, no gradual transition, no blur between them, a sharp yet visually harmonious junction, both sections unified by the same camera, lens, film stock, lighting, palette and film grain structure.
