rendered in luxury gold foil birthday style. Letters in premium metallic gold — gradient from bright gold highlight to deep warm shadow, subtle surface sheen and fine gold dust particles. Deep dark background (near-black or deep navy). Clean minimal composition — no colorful confetti, no colored balloons. Optional fine gold border frame or minimal gold star scatter (≤8 pieces). Wide letter spacing. High contrast gold-on-dark. Premium printing quality aesthetic. FontVibe as luxury gold foil letters centered, filling 70% of frame width, wide tracking. Scene: a high-end type foundry or luxury brand studio aesthetic — very dark charcoal background with a very subtle warm gradient suggesting architectural depth. The gold letters are pressed against a softly lit dark stone or matte black surface, casting a precise warm shadow downward. Warm directional light from upper-left illuminates letter faces — brilliant gold highlights on top, deep warm shadow at base. Background: very softly blurred gold foil sheets and a fountain pen on a dark desk surface suggest premium craftsmanship context. Fine gold border frame. Minimal gold star scatter. Refined, premium, design-institution aesthetic. Zero colorful elements.
