大膽蛋塔開幕海報

Goal: Create a bold minimalist food advertisement poster for a bakery opening, centered on one photorealistic Portuguese-style egg tart.

Canvas: Vertical poster in 3:4 aspect ratio, soft pale pink background with subtle smooth gradient, no borders or watermark.

Layout: At the very top, place an enormous uppercase red headline reading {argument name="top headline" default="WE'RE"}, using a heavy geometric sans-serif font, spanning nearly the full width. Directly underneath, centered, add one rounded pill outline in red containing the uppercase text {argument name="product label" default="DELICIOUS EGG TARTS"}. In the middle of the poster, place exactly 1 large egg tart floating on the pink background, photographed realistically with no plate or hands. Below the tart, centered, add one smaller rounded red outline pill containing the uppercase text {argument name="happy hour text" default="HAPPY HOUR: 6AM"}. At the bottom, place an enormous uppercase red word reading {argument name="bottom headline" default="OPEN"}, using the same heavy sans-serif font, spanning almost the full width.

Subject details: The egg tart should be golden brown with a flaky layered puff-pastry crust, glossy yellow custard filling, dark caramelized blister spots, and a light dusting of powdered sugar across the top. Make it appetizing, sharply detailed, and studio-lit, with a subtle natural shadow only if needed.

Visual style: Modern pop-art bakery poster, high contrast red typography on pastel pink, clean negative space, centered alignment, crisp commercial food photography, bright but soft lighting.

Text constraints: Use exactly 4 visible text elements: 1 top headline, 1 product-label pill, 1 happy-hour pill, and 1 bottom headline. Keep all typography bright red, uppercase, bold, and clean. Do not add any extra logos, icons, prices, addresses, small print, or decorative objects.
