为[CITY]设计一张4:5的高端收藏级邮票海报，整个构图是一枚占据全画幅的巨型奢华邮票，如同稀有的国家级艺术品。邮票应占据画布主体，具有巨大的触感齿孔边缘、优雅的雕刻边框和沉浸式的物体导向构图。
风格：手工水粉插画结合丝网印刷海报美学、社论旅行艺术和博物馆级极简印刷效果。作品应通过建筑、天际线节奏、交通、景观、文化符号、气候、几何形状和环境标识捕捉城市的真实氛围，以优雅的图形形式而非陈旧的旅游明信片形式进行诠释。
构图应具有动态和不对称感。一个主导城市元素应斜向穿过邮票，次要形式围绕其流动以创造深度和运动感。保留刻意的留白以营造高端精致感。避免杂乱和过度写实的细节。
排版是设计的核心部分。城市名称“[CITY]”必须以巨大的形式直接融入邮票艺术中，如同奢华的刊头，通过遮罩、重叠或深度与插画互动。排版风格应自然适配城市个性：历史城市使用精致的衬线体，未来城市使用干练的现代无衬线体（Grotesk），沿海或热带城市使用柔软流动的形式，艺术城市使用富有表现力的手工字体。
次要排版保持极简和真实：微小的面值数字、AIR MAIL / POST 文字、发行年份、序列号、微型邮戳、雕刻信息条以及整合在边框中的细微消戳细节，不要干扰画面构图。
光影应具有高端收藏级印刷摄影质感：柔和的定向高光展现触感哑光纸纹理、压凸墨迹边缘、细微的印刷压力、齿孔边缘的精致阴影以及细腻的墨水密度。不要戏剧性的电影灯光。
色调必须智能适配城市，同时保持克制、优雅且富有氛围感：
• 沿海 → 青色、珊瑚色、褪色奶油色
• 沙漠 → 赤陶色、藏红花色、灰粉色
• 霓虹巨型城市 → 钴蓝色、洋红色、深海军蓝
• 历史感 → 橄榄绿、羊皮纸色、酒红色
• 热带 → 祖母绿、芒果色、海蓝色
• 极北雪城 → 冰蓝色、暗松绿、银灰色
最终效果应像是在豪华博物馆设计商店售卖的极罕见纪念邮票——精致、具有触感、沉浸式、可收藏且永恒。
负面提示：平庸的旅行海报、漂浮的地标、纪念品审美、拥挤的拼贴、过度的排版、虚假的复古做旧、素材库矢量图标、随机渐变、低细节插画、居中布局、平庸的邮票样机、噪点纹理、过度渲染的写实。
Design a premium 4:5 collectible postal-stamp poster for [CITY], where the entire composition is one monumental luxury postage stamp filling the frame edge-to-edge like a rare national artifact. The stamp should dominate the canvas with oversized tactile perforation edges, elegant engraved borders, and immersive object-focused composition.
Style: handcrafted gouache illustration blended with silkscreen poster aesthetics, editorial travel art, and museum-grade print minimalism. The artwork should capture the city’s true atmosphere through architecture, skyline rhythm, transportation, landscape, cultural motifs, climate, geometry, and environmental identity - interpreted in elegant graphic forms rather than cliché tourist postcards.
The composition should feel dynamic and asymmetric. One dominant city element should rise diagonally through the stamp while secondary forms flow around it to create depth and movement. Preserve intentional negative space for a refined premium feel. Avoid clutter and over-detailed realism.
Typography is a major part of the design. The city name “[CITY]” must appear massive and integrated directly into the stamp artwork like a luxury masthead, partially interacting with the illustration through masking, overlap, or depth. Typography style should adapt naturally to the city’s personality — refined serif for historic cities, sleek modern grotesk for futuristic cities, softer flowing forms for coastal or tropical cities, expressive handcrafted lettering for artistic cities.
Keep all secondary typography minimal and authentic: tiny denomination number, AIR MAIL / POST text, issue year, serial numbers, microscopic postal marks, engraved information strip, and subtle cancellation details integrated into the borders without cluttering the composition.
Lighting should feel like premium collectible print photography: soft directional highlights revealing tactile matte paper grain, embossed ink edges, subtle print pressure, delicate shadow depth around perforation cuts, and refined ink density. No dramatic cinematic lighting.
Color palette must intelligently adapt to the city while remaining restrained, elegant, and atmospheric:
• coastal → turquoise, coral, faded cream
• desert → terracotta, saffron, dusty pink
• neon megacity → cobalt, magenta, deep navy
• historic → olive, parchment, burgundy
• tropical → emerald, mango, sea blue
• snowy northern → icy blue, muted pine, silver gray
Final result should feel like an ultra-rare commemorative stamp sold in a luxury museum design store — sophisticated, tactile, immersive, collectible, and timeless.
Negative: generic travel posters, floating landmarks, souvenir aesthetics, busy collages, excessive typography, fake vintage distress, stock vector icons, random gradients, low-detail illustration, centered layouts, generic stamp mockups, noisy textures, over-rendered realism.
