Minimalist Business Exhibition Poster

Generate a minimalist business exhibition poster around {argument name="subject" default="any subject"}. The image features a soft, gentle monochromatic background ranging from olive to grass green, complemented by subtle paper textures and soft ambient lighting. The lower half uses fine line drawing combined with soft shading to present a city skyline silhouette, with prominent foreground buildings on the left and right creating a sense of layered spatial depth. The upper half features a large area of breathable negative space, with oversized bright white sans-serif bold numbers and core theme identifiers centered at the top. Micro icons and auxiliary text lines are scattered systematically. Semi-transparent large-font watermark text runs vertically along the right edge as a visual anchor. The typography is clean and orderly, blending perfectly with the architectural lines to present a modern, high-quality, and elegant business invitation aesthetic.
