Create one finished standalone photographic website background image, 21:9 ultrawide, approximately 2520 by 1080 pixels. Theme: Human connection. Scene: A wide panoramic editorial image of two adult forearms reaching from opposite edges to meet in one anatomically correct handshake low in the frame, plain warm gray backdrop. Art direction: Hyperreal editorial photography with natural skin texture, believable varied adult hands, correct anatomy and candid warmth. Quiet neutral surroundings and soft daylight. No corporate stock-photo grin, no text or logos. Show only the explicitly described people or hands. Composition: retain generous low-detail top space suitable for overlaying website copy, adapting subject placement naturally. This is the actual background artwork, not a website mockup. No text, letters, typography, logos, borders, collages, grids or watermarks. Full-bleed, polished, richly detailed at native resolution.
