<role> You are a senior art director and prompt engineer for high-end sports brand poster design, specializing in modern Chinese Guochao (national-trend) visual identity. </role> <task> Produce a single, production-ready text-to-image prompt for a 9:16 vertical invitation poster announcing the Guangdong Provincial City Football Super League ([league nickname]). </task> <context> - League: [league full name] ([league nickname]) - Event type: Invitation - Date: [event date] - Venue: [venue name] - The poster merges Guangdong city landmarks and culture along a single motion path: [landmark list], plus [cultural elements list]. - Required headline text stack: [main title]; vertical [short league label] in large handwritten calligraphy; vertical [invitation label]. </context> <constraints> 1. Composition: S-shaped flow rising bottom to top; a dynamic energy stream shaped by a ball's motion trail traverses the frame; one glowing football anchors the center with trajectory streaks and energy light effects. 2. Elements: integrate [landmark list] along the S-curve; render every element as line drawing + partial color blocks + negative space, with layered depth and near/far虚实 balance; add abstract football player silhouettes with minimized facial detail to amplify motion and competitive energy while the football stays the primary focal point. 3. Typography: [main title] — horizontal, top center, medium size, Song typeface. [short league label] — centered vertical, large, handwritten calligraphy art font. [invitation label] — vertical, medium size, Song typeface, generous letter spacing. Bottom center: row 1 horizontal [event date], small, Song typeface; row 2 horizontal [venue name], small, Song typeface. Reserve clean breathing room around all text blocks. 4. Style: modern Guochao premium poster, minimal yet designed, refined, clean, unified, blending Eastern aesthetics with modern sports imagery; balanced layout, precise detail, uncluttered, cinematic lighting, 8K resolution. 5. Color: high yet restrained saturation; Chinese red as dominant, cyan-blue as support, gold as highlight accents; high contrast without clutter; brand-level visual impact. 6. Finish: add elegant auspicious-cloud and water-ripple motifs derived from traditional Chinese patterns plus floating light particles for motion and vitality. 7. Keep all specified text legible and correctly spelled; leave the lower text area uncluttered. </constraints> <format> Return one continuous, comma-separated descriptive prompt of 150–250 words, no headings, no bullet points, no explanation. </format> <tone> Visual, precise, professional, and evocative — the language of a creative brief. </tone> Begin now: output the final image prompt only.
