Create a finished, wide horizontal birthday backdrop on a clean, plain warm-white studio background. Center two tiers of dimensional lettering with generous clear margins: the dominant name “Sofia” across the middle, large and immediately readable from a distance; above it, a smaller but bold line reading “HAPPY BIRTHDAY”. Keep the composition focused on the lettering, with no extra words, props, confetti, borders, or background objects. Build every letter as a massive chunky 3D block with thick, uniform extrusion about 55% of its letter height and crisp, sharp edges where the front meets the sides. Coat the front faces in ultra-glossy hard-candy lacquer, with natural bright specular highlights graduating into deep saturated color. Give each adjacent letter a different vivid hue family: “Sofia” in cherry red, electric blue, sunshine yellow, lime green, and hot orange, respectively. Use similarly varied saturated colors for “HAPPY BIRTHDAY,” ensuring neighboring letters never share a hue family. Extrusion sides are a darker shade of each letter’s face color, with strong, immediate face-to-depth contrast. Cast long, crisp shadows diagonally down and right at a consistent 45-degree angle, about 45% of the letter height. A strong directional key light from upper left creates the glossy reflections. Keep the backdrop minimal and bright so all visual impact comes from the colorful dimensional lettering. Render the spelling exactly as quoted; no other text.
