Chinese Brushstroke Shanghai Poster

Prompt

A refined Chinese city-promotion poster on a warm off-white textured paper background, with a large traditional calligraphy brush entering from the lower left corner and sweeping upward to create a single dramatic brushstroke that transforms into a miniature sculpted cityscape. The brushstroke should look like layered ink, watercolor, and carved relief combined, with flowing edges and a dynamic curved shape like a cresting wave. Inside the brushstroke, depict {argument name="city name" default="Shanghai"} as an elegant miniature diorama in a Chinese artistic fusion style: the Oriental Pearl Tower, Shanghai Tower, and the historic Bund clock building rendered as highly detailed architectural models rising from the painted stroke. Add a winding blue river in the foreground with 2 small boats, terraced embankments, stylized traditional cloud motifs curling around the buildings, and textured rocky forms and autumn-toned trees integrated into the composition. Use a palette of muted teal blue, stone beige, soft gray, rust red, and ink black. The overall style should blend Chinese ink painting, paper sculpture, bas-relief miniature architecture, and premium tourism poster design, with precise craftsmanship, soft studio lighting, subtle shadows, lots of negative space, and a calm luxurious editorial feel. Place large black Chinese calligraphy near the lower left reading {argument name="main title text" default="上海"}, and beneath it add 2 lines of smaller Chinese promotional text: {argument name="tagline line 1" default="申江潮起千帆竞，海上风来万象新"} and {argument name="tagline line 2" default="海派都会・东方门户"}. Vertical composition, centered artwork with generous margins, ultra-clean layout, high detail, premium travel campaign aesthetic.
