Vertical commercial poste

Vertical commercial poster, 1080×1350px, dark brown to warm gold gradient background with subtle light flare at top. Center: a massive 3D numeral "25" composed entirely of tightly packed dark roasted coffee beans, visible gaps and natural shadows between beans, faint golden reflection on bean surfaces. Below the number: small white text "Days until 2026 Hainan International Coffee Expo opens". Behind the number: Haikou city skyline silhouette, dominated by the Hainan International Convention & Exhibition Center's flowing dome architecture, rendered in semi-transparent warm gold gradient, ghostly and atmospheric. Scattered coffee beans and leaves around the number with shallow depth-of-field blur. Bottom: dark brown block with white text info — "Aug 14-16, 2026", "Hainan International Convention Center, Haikou", "500+ Exhibitors | 40,000㎡+". Clean and grand composition, "25" as absolute visual focal point, strong countdown urgency. Warm gold tones, cinematic lighting, print quality.
