「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. Birthday celebration typographic centerpiece — "Happy Birthday" in liquid 3D gold luxury letterforms, centered in frame. Pure deep black background. The phrase glows with festive warmth: champagne-white specular peaks on every bevel face, deep amber shadows in the letterform recesses, warm amber light pool beneath. The cast-gold physical mass of each letter makes "Happy Birthday" feel like the world's most premium greeting card headline.
