Create a polished, celebratory birthday backdrop in a wide 3:2 composition. The dominant centerpiece is the exact name “Sofia”, large and unmistakable, rendered as massive chunky 3D display lettering with thick uniform extrusion about half the letter height. Preserve the spelling and capitalization: uppercase S followed by lowercase o, f, i, a. Give neighboring letters distinct vivid colors in order: cherry red, electric blue, sunshine yellow, lime green, and hot orange. The front faces are ultra-glossy hard-candy lacquer with crisp natural highlights and saturated color; extrusion sides are a darker shade of each face color. Keep face-to-side edges sharp, with no bevels. Above the name, add the smaller exact line “HAPPY BIRTHDAY” in compact, clean, glossy multicolored 3D lettering, clearly subordinate and centered. No other words or numerals. Set the lettering against a minimal warm-white studio wall and floor, with generous clear space around the name. A strong directional light from the upper left creates bright lacquer reflections and long, crisp cast shadows falling diagonally at 45 degrees. Add only a few tiny, scattered pieces of colorful confetti near the floor as a restrained birthday cue; keep the environment uncluttered and the lettering as the entire focus. Slight low viewing angle, frontal enough to read every letter cleanly, with a subtle floor reflection. Professional, vivid, joyful dimensional typography, suitable as a birthday party photo backdrop.
