“Happy Birthday”是使用 FontVibe AI 创作的儿童礼物文字效果。粉、黄、蓝、绿的亮面铝膜气球字母，飘在小气球、彩纸屑、星星和爱心之间，背景是浅天蓝色。

a playful, joyful kids-gift piece — bright, fun and magical. SURFACE / STYLE: the lettering is rendered for kids — glossy chunky 3D toy letters, shiny foil balloons, or chunky waxy crayon strokes — bright and tactile, depending on the chosen font, with cute stars, hearts and sparkle scattered around. SCENE ATMOSPHERE: a cheerful party setting — confetti, balloons, rainbow trails and a sprinkle of magic sparkle. PALETTE: bright candy colors — bubblegum pink, sunshine yellow, sky blue and lime green — maximum saturation and maximum fun, never muted or dark. LETTERFORM PRIORITY: when the chosen font carries its own treatment (kids balloon, kids crayon, chunky 3D, bubbly or rounded display), that font's letterform takes priority and owns the letters; this style governs the bright candy color, the stars-hearts-sparkle and the cheerful party scene. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as glossy chunky 3D toy letters in bright candy colors with cute stars, hearts and rainbow sparkle, so the fun kids energy always reads. A square 1:1 party graphic. 'Happy Birthday' large and dominant as foil-balloon letters with confetti. Joyful mood, no devices.
