上海白玉兰早安海报

Goal: Create a refined horizontal city morning poster for {argument name="city name" default="Shanghai"}, combining macro botanical photography with a quiet editorial information layer and a misty urban skyline.

Canvas: Wide 16:9 poster, clean off-white and pale gray background, airy negative space, soft morning light, premium magazine layout.

Main subject: Use exactly 2 oversized white magnolia blossoms with realistic macro texture: 1 large cropped blossom entering from the upper-right corner with translucent ivory petals and visible beige-green stamens, and 1 large cropped blossom entering from the lower-left corner. A slender green magnolia stem runs diagonally from the upper-right flower down toward the lower-left flower, lightly crossing the center and creating suspended tension.

Background: Faint low-contrast Shanghai skyline along the lower third, softened by haze and sea mist, with the Oriental Pearl Tower visible near the center-right. Add a calm reflective waterfront at the bottom, extremely subtle and desaturated.

Central typography: Place large black vertical Chinese title text “上海” above “早安” in the center, bold high-contrast serif style. Overlay a purple handwritten italic script reading “Shanghai” diagonally across the title, as if drawn with a marker. Keep the typography sharp and balanced against the soft flowers.

Information layer: Include exactly 5 small editorial UI/text elements: 1 rounded pill at top-left reading “城市 / 上海” with a small purple dot; 1 keyword line at left reading “关键词 / 海风 外滩 霞光 玉兰” followed by a thin horizontal rule and small endpoint circle; 1 quote card at right with a purple quotation mark, the text “早安，让风把灵感吹亮。” and date “2026-07-11”; 1 vertical coordinate tag at far right reading “坐标 / SH-0711” with a small globe icon and purple dot below; 1 bottom-center copyright line reading “© 版权 / CITY POSTER ARCHIVE 2026”.

Visual style: Minimal Chinese editorial poster, macro physical texture, elegant high-key lighting, shallow depth of field, soft fog, crisp black typography, small purple accent color, abundant breathing room, precise alignment, no clutter.

Constraints: Keep all visible text exactly as specified, use exactly 2 magnolia blossoms and exactly 5 information elements, avoid extra logos or watermarks, avoid saturated colors, maintain a calm premium morning aesthetic.
