极简商务展会海报橄榄绿线描城市天际线

Generate a minimalist business exhibition poster around any subject object. The image uses a soft-toned, mild monochromatic background ranging from olive green to grass green, complemented by subtle paper micro-textures and soft ambient light and shadow. The lower half features a city skyline architectural silhouette group presented in a combination of fine line drawing and light sketch tones; foreground buildings on the left and right are prominently heightened, while the middle is supported by layered mid-to-distant contours, outlining a landmark architectural background with a great sense of layering and spatial depth. The upper half leaves a large area of 'breathing' negative space, with oversized bright white sans-serif bold numbers and key booth numbers/core theme identifiers placed in the center at the top, and micro-icons (such as clocks, location pointers), auxiliary small-font English, and Chinese information lines arranged in a staggered manner above and below. Large-font translucent light green sans-serif watermark text runs vertically through the right edge, forming a visual anchor on the right. The overall typography is clear and regular, the text hierarchy has a strong sense of order, and the line-drawing architecture perfectly blends with the soft monochromatic tone, presenting a modern, high-quality, elegant, and professional visual atmosphere for an exhibition invitation.
