Luminous Birthday Card

Designed with a deep indigo background, this card centres the words “HAPPY BIRTHDAY” in large, puffy, glossy letters that look like candy-coated balloons 🎉. The letters are arranged across the middle and shine in a mix of sunny yellow, bright blue, warm red, orange, and pink, with gentle gradients that make them feel rounded and close. Around the text, a glowing border frames the scene, shifting through hot pink, electric blue, and purple like a soft neon glow. The dark backdrop is sprinkled with tiny floating shapes that feel like a friendly crowd gathering around the message, adding a cozy, together-at-the-party mood. Small dots, diamonds, stars, and loose squiggles drift around as if they’re dancing in the light, giving the layout a lively rhythm 🎁. Subtle highlights and faint shadows under the letters add depth, as though the words are hovering just above the surface. Scattered across the background are glowing spheres and star-like shapes in bright complementary colours, spaced evenly around the central text and inside the neon frame.
