Sweet Birthday Glow Effect Card

The front design shows “HAPPY BIRTHDAY” centred in large capital letters, with “HAPPY” shifting from bright yellow into pink and “BIRTHDAY” moving into a cool cyan glow 🎉. The lower halves of the letters have a drippy, bubbly texture that looks like sparkling frosting sliding downward 🎂. Everything sits on a deep black background that makes the colours feel like they’re lit from within. Surrounding the words is a scattered field of interlocking gear-like shapes in many sizes, some with spoke details and a few with simple symbol cutouts. The neon palette jumps between lime green, orange, electric blue, sunny yellow, and purple, and each shape has a soft halo that overlaps slightly with its neighbours like they’re drawn together. Small four-point stars and tiny dots float around the layout like confetti, adding a flirty twinkle that feels like a shared moment under party lights. The text stays in the middle while the glowing gears and star specks fill the edges and corners, creating a bright frame against the dark backdrop.
