「Happy Birthday」は FontVibe AI で作成したラグジュアリーゴールドの文字エフェクトです。細かな箔のしわがある重厚な鋳造金の大文字。くぼみには深い琥珀色の影、頂点には明るい反射。一灯のスポットライトで黒の中に浮かびます。

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.
