“SAMSUNG Galaxy S24 Ultra”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. 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. 'SAMSUNG Galaxy S24 Ultra' centered as a balanced two-line title — 'SAMSUNG' / 'Galaxy S24 Ultra' — each line filling 75% of frame width. Pure deep black background. Dramatic upper-left spotlight: letter faces blazing liquid 24K warm gold, recesses pooling in deep amber-brown, bevel edges carrying razor-bright champagne-white specular lines. Crisp cast shadows angle to lower-right. Warm amber light pools gently on the dark ground plane beneath each letter. Diamond dust particles — tiny prismatic sparks — suspended near letter edges catching the spotlight in sharp bright points. Atmosphere: luxury perfume counter, premium awards stage, high fashion editorial. Heavyweight golden presence.
