「Happy Birthday!」は FontVibe AI で作成した溶けるフォントの文字エフェクトです。下から液化していく艶のあるオレンジレッドの文字。溶けた滴、ゆがんだ下端、暗いチャコールの床に光る水たまり。

letter material liquefying and flowing downward under heat — lower portions lose structural integrity, edges softening and rounding outward as gravity pulls the molten mass down. Multiple drips of varying thickness: one to two thick primary flows with slight bulge at origin and teardrop termination, two to three medium streams, fine capillary trails between them. Surface tension visible at drip necks. Viscous pooling accumulates at the letter base with a faint wet-surface sheen. When no specific material is defined, the default melt color is warm amber-to-deep-orange — the natural thermal color of heated translucent material. "Happy Birthday!" rendered as the dominant celebration graphic in translucent birthday-cake wax, solid and glossy across the upper surfaces then liquefying under candle heat. The wax shifts from bright golden amber at the heated edges to saturated tangerine-orange and deep caramel-orange in the descending flows. Lower letter portions soften, round outward, and lose structural integrity; visible surface tension gathers at each drip neck. Include one to two thick molten streams with swollen origins and sharp teardrop termini, two to three medium drips, and fine capillary trails between them. A shallow viscous wax pool collects beneath the lettering, with rippled edges, tiny trapped air bubbles, and a wet high-gloss sheen. Small birthday candles emerge behind the text, their flames casting tight yellow-white highlights across the convex wax skin; scattered confetti flecks and a few soft-focus metallic streamers remain secondary. Deep charcoal backdrop with a faint burnt-amber heat haze, subtle rising smoke wisps, and a warm reflected glow near the base. Overhead key light plus candlelight, crisp specular arcs, ray-traced subsurface scattering, detailed molten material, sharp cast shadows, high-resolution studio product render. Preserve clear, fully readable rendered text: "Happy Birthday!".
