「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. Premium birthday card flat-lay — a thick matte black greeting card open at 45°, placed on a dark marble surface. Inside the card: "Happy Birthday" in raised gold 3D luxury letterforms — hot-stamped and embossed, with champagne-white highlights on the raised edges and warm amber pooling in the letterform gaps. A single white rose and gold confetti dots visible beside the card. Luxury greeting card product photography, editorial overhead shot.
