“Happy Birthday”是使用 FontVibe AI 创作的奢华金箔文字效果。厚重的铸金大写字母带细密箔纹，凹处是深琥珀阴影、高点是明亮反光，在单束聚光下孤立于黑色背景。

Liquid 24-karat gold molten surface — microscopic foil crinkle texture across all faces, deep amber pooling in recesses, rich warm gold across main surfaces, razor-bright champagne-white specular peaks where direct light strikes. Subtle embossed relief depth — each letterform has physical mass and weight, like cast or stamped precious metal with visible surface thickness. Single dramatic spotlight from upper-left, angled 45°, creates crisp directional shadow and intense highlight contrast. Background: pure deep black — zero ambient fill, forcing all luminosity to belong to the gold. Phone screen in portrait mode showing an Instagram Story being created — the Story canvas has a rich dark background with "Happy Birthday" in two lines of 3D gold luxury letterforms as the main text sticker, positioned center of the Story. The Instagram Story creation interface is visible: sticker tray at top, text toolbar, share controls at the bottom edge of the screen. The gold text stands out as the obvious celebration centerpiece. Realistic Instagram Story content creation context, the kind of premium birthday Story a lifestyle creator posts.
