This greeting card features a night-dark background with two glowing words that feel like an inviting sign in a late-night city window 🎉. The top word, “HAPPY,” sits centered near the upper half in flowing, connected lettering that looks like light tubing, shining in warm yellow with a soft halo. Its looping strokes lean slightly forward, like a friendly note shared between close friends across a table. Below it, “BIRTHDAY” is larger and centered, set in tall uppercase letters built from many close, parallel lines of light that give a lightly woven look. The color starts as hot pink on the left and shifts gradually into a gentle purple toward the right, adding depth and a tender, celebratory glow 🎂. The spacing between the two lines leaves a calm pocket of dark space, making the words feel like they’re floating together in the same spotlight. A faint aura surrounds each letter, and the black backdrop stays smooth and uninterrupted behind the yellow “HAPPY” and the pink-to-purple “BIRTHDAY.”
