Affiche d'Anniversaire Luxueuse en Papier Sculpté

A luxury editorial birthday poster in a vertical 3:4 portrait orientation. A massive number [3] is carved deeply into a snow-white textured paper wall as a clean architectural niche, featuring thick rounded edges, bevels, and realistic inner shadows. Inside the hollow number is a muted pale blue-gray recess. A toddler boy sits in the lower opening of the carved number, slightly overlapping the front threshold, wearing a plain white short-sleeve T-shirt and cuffed light blue jeans, barefoot in a relaxed seated pose with one knee raised; his face is softly anonymized and out of focus while keeping realistic hair and clothing texture. Inside the carved number are 12 balloons in navy blue, powder blue, white, and soft gray with delicate strings, arranged throughout the upper, middle, and lower chambers, along with 5 small white floral bouquets tucked into the corners and beside the child. Centered neatly below the number are three lines of elegant serif typography: Line 1: "[SAAD]" in large, embossed metallic gold uppercase letters with a subtle 3D sheen. Line 2: "[CHAPTER 28]" in small dark navy uppercase serif. Line 3: "[365 MORE DAYS OF MIRACLES]" in slightly smaller dark navy uppercase serif. Soft warm studio lighting, realistic papercraft architectural volume, clean negative space, polished luxury aesthetic.
