“SPARK”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. A designer's MacBook Pro open on a modern minimalist desk — soft natural daylight from a window at the left, clean white desk surface, design tools and notebooks subtly visible around the laptop. The MacBook screen shows a Figma design workspace with a project open: "SPARK" as a 3D text asset prominently placed in the design canvas — bold 3D beveled letters, cherry red and electric blue alternating, glossy candy surface, intense specular highlights — displayed as a design component in the Figma frame. Figma UI panels and layers visible around the canvas. MacBook screen and the Figma design are sharp focal point. Professional design workspace atmosphere — 16:9 scene.
