Luminous Birthday Orb Card

This design shows the words “Happy Birthday” centered in large, flowing letters that look softly lit, shifting from icy blue into deep pink 🎉. The lettering sits against a near-black background, giving it a night-sky feel where the glow seems to spill outward. Around the message, glossy round orbs float at different sizes, like bubbles or glass marbles drifting close together as if keeping each other company. Some orbs are sharp and jewel-like with bright highlights, while others fade into gentle, out-of-focus circles in pink, teal, and violet. Tiny specks of light appear inside a few of the clearer spheres, like little constellations that add a tender, close-knit mood to the scene 🎂. The main text stays in the middle, with the brightest color concentrated along the curves of the letters and softer light feathering into the dark space. Along the edges and behind the words, clusters of spheres create depth, with crisp reflections on the nearest orbs and hazy magenta-and-cyan halos farther back.
